Paint my world (Sherlock X OC)

Ms and Mr

So my Google map confirmed this is the house I was looking for. Not that I didn't know, but I was just confirming it. 'okay let's go' I thought to myself before stepping towards the main entrance. Standing infront of it I knocked at the door. 'coming dear' came the reply from the other side, it seemed it's an old woman's voice. And so it was,
"oh good morning dear." greeted the old lady with the biggest and sweetest smile.
"hi, and yes good morning!" I replied, I hope my smile was sweet enough for her, "is it Rosamund ... I mean Dr John Watson's residence?"
She seemed a little baffled by my enquiry, "Dr John watson?" she asked.
"um yes?" I replied.
"not Sherlock Holmes?" her question made it clear why she was confused, most people comes here to ask Mr Sherlock Holmes's help. And the first person they looks for is, the detective himself.
"oh actually I'm here for Rosamund Watson mostly ". I clarified.
"ah I see, John did tell me, come in then" letting me in she called John watson and he appeared in no time, seeing me standing he gestured me to come in, "come upstairs Ms Ball."
I followed him to upstairs and stood infront of his flat entrance.
"do come in" I did as he said and closed the door halfway behind me, "sorry forgot your name -"
"Melody, I'm Melody Ball" I answered.
"Melody?" came from inside, a rather deep voice and we didn't have to search for it because the person appeared himself. And quite apparently it was the aloof detective as people say, Mr Sherlock Holmes. "Melody?" he called my name again.
"yes it's me sir.." I cringed at me referring him as sir rather than Mr Holmes, but I was showing respect to him so I just hoped he didn't mind.
"don't call me sir" he replied sternly "Mr Holmes would be fine".
"yes ofcourse, sorry for calling you sir it was -" before I could say the entire sentence we stared at a little girl running towards us, and before embracing his father she embraced Sherlock Holmes. I must admit, children has always been on my nerves but Rosamund Watson looked as if ... we can get along.
"that's my daughter Rosamund" said Dr watson indicating towards the tiny lady "and Sherlock is her god father, they're inseparable".
That I could guess from the scene.
"Rosie" he called, and she went running towards her father, "we call her Rosie, and Rosie" he said looking at his daughter "she's Ms Melody Ball, your drawing teacher".
Rosamund looked at me and smiled, even though she seemed a little shy.
"is she interested in drawing that much though?" enquired the detective, his disbelief was evident that his god daughter can be interested in simple things like... drawing.
"yes, remember she drew you and bees?" reminded John Watson.
"hmmm" the detective just hummed, clearly he doesn't remember it.
"on the fridge Sherlock" John Watson's voice held a  bit of annoyance.  Sherlock Holmes followed his instructions and turned to see the fridge and nodded, the drawing was stuck with a cute fridge magnet.
"it's actually pretty nice" I went closer to it, I was quite fascinated by the little girl's drawing. At that age, it was pretty good, "lovely" I said before turning to Rosamund, "do you really love drawing Rosamund?"
"yes I do" she sounded as cute as she looked, her shyness faded and she talked more confidently.
"so Ms ball" asked her father, "select your days".
"yes ofcourse" I thought of my schedule, not like there was much, being a drawing teacher was never on my list. Patience is not my thing, that made me yell at an author for making me do too many changes on some illustrations and I lost my job as a book illustrator for a publishing house. "how about Monday, Wednesday and Friday, of every week".
John Watson was about to perhaps agree with it while Rosamund's Godfather interrupted, "yeah works fine, I guess, in evening ofcourse, innit Melody?"
He asked me to call him Mr Holmes while he for not even once called me Ms Ball, straight to Melody, and I felt disrespected.
"yes ofcourse, I'm aware of her having school in the morning... isn't it ... Mr Holmes?" I tried to emphasize 'mr holmes' so he get's my point.
"that's right, John?" he looked at John Watson to find out if he agrees.
"yes it's fine" he agreed.
"I hope Rosie will learn alot from you Melody" again, not even Ms Melody... just melody? As I said I'm a person who lacks patience so I let my frustration take the lead and uttered,
"I think she will, Sherlock" and I regretted it, their expression said how surprised they were, where even Rosie stood staring at us.
"excuse me?" the detective was ... annoyed ofcourse, and that made me gulp.
"you..." I didn't know if I should explain but guess I wasn't left with much choices, "you called me Melody, I'm a stranger to you, a... a drawing teacher to your God daughter and yet you didn't call me Ms melody or Ms Ball... so I -"
"so you did the same" he said, "how old are you... Melody".
'Oh this man' I thought fuming, "how rude to ask a woman's age".
"was just being polite, you're twenty two" he said and I was stunned, because he was right.
"how did you..."
"I can deduce, I don't buy that you don't know that about me" he stated and yes I knew, but witnessing it was like a dream... no no I was really mad so it wasn't that fascinating.
"And I must remind you, I'm older than you, I'm allowed to call you Melody, you aren't".
I wanted to ask how old is he but I didn't dare.
"yeah he's 41 and I'm 43" clarified John watson.
"so I guess" I looked at John Watson, "my behaviour and lack of patience made me lose this job as well, and I don't blame you, any of you" I said it looking at Sherlock Holmes, "thanks for the offer by the way, have a nice day" saying so I sprinted towards the door.
"Melody wait" again the same deep voice calling me by my name. I stopped and turned, trying to look indifferent.
"yes Mr Holmes?" perhaps he was right, he's 19 years older than me, I should respect him.
"We're having you for your talent in illustration not for... but we'd definitely like you to be patience with Rosie." he said and I nodded, "we'll give you this chance".
I'm not sure if my expression told him how grateful I was for the chance, guess it did, he reads faces like books, he's Sherlock Holmes.
"Monday then" he asked for confirmation.
"yes, Monday, see you Dr watson, Rosamund and..." looking at Sherlock I fumbled through the names I should call him, "Mr... Mr Sherlock Holmes".
Opening the door, went straight to downstairs.
"Sherlock works fine" came from his flat, I looked up to see the detective permitting me to call him by his name, "if it's not intended for disrespect."
I nodded before opening the main entrance and came outside. Puzzled, yes I was puzzled, everything that happened there kept replaying in my head, shaking my head I walked towards the subway, suppressing the urge to turn back and see if any of them is at the window... fine fine... if Sherlock Holmes is at the window, perhaps not, or perhaps yes. Yet heading over to subway seemed most important, after all I'm not unemployed anymore, I have a job again, a real job, again.
