Harry Potter's sister

Diagon Alley

Hagrid,Lily and Harry made their way through London.
"So are yo excited about buying yo' firs' wand?"
"Yes"Both twins said at the Same time,smiling as they did so.
Hagrid entered the pub in which the twins realize that they are famous because every body made a fuss at their arrival.
"Welcome to Diagon alley!"Hagrid beamed.
"Wow!"
"First of all we mus' go to gringrotts"
"What's that?"
"The wizards bank"
"Hello Mr.Goblin,ide like to have a go at the potters vault"The giant said the moment he set foot in Gringrots.
The goblin stared at Hagrid as if deciding if he was a thief or not before handing him the key.
Harry and lily grabbed their money from the vaults and watched suspiciously as Hagrid got a small package from a vault they knew not.
"Firs' let's go buy yo robes"
"From where do we buy them sir ?"
"You wait and see"
They entered Madame Malkin's  shop for all occasions.
Hagrid seated himself on a rickety chair,which yelled in protest,and by yelled I mean collapsed.
"Careful Hagrid."The shop's owner said warningly.
Hagrid went hot red as his face flushed in embarrassment. 
"Sorry,Harry lily I'll go and buy something, wait me here"
"Are you going to Hogwarts?"A blonde asked.
"Yes, are you?"Harry asked.
"Of course I am"
"You're done kids"Madame Malkin said just in time for Hagrid arrived carrying an owl cage and a ginger kitten.
He seamed to be having trouble carrying them since the cat didn't give the angry owl a rest.
"These are your birthday presents"he said smiling warmly.
"Thank you so much!"the twins said simultaneously,eyes lightning up as their stared at hazel brown ones.
"Now let's go get your wands!"
"Harry Potter"Oliver the wand maker said softly the moment Harry set foot in the wands' shop.Lily Potter,what an honor
"Hello sir"they said at the same time taking Olivander by surprise. 
"So let's try Harry first"he said handing Harry a wand.
"Give it a swish"olive spoke when harry did nothing but stare at it as if it was celebrity.
Harry did as he was told resulting all the wand boxes to fall on Olive's head.
"Sir!"
"I'm alright,I'm alright"he assured.
He handed him another wand ,which caused The door to get blasted open.
"Wow Harry,nice shot"Lily implored,earning Harry's smile and a chuckle form Olivander.
"True indeed Mrs.potter"he said as he repaired the door.
After trying another 20 wands Harry  found one that suited him.
"Now it's your turn"Harry said.
Olive handed Lily a wand,she gave it a swish and the result caused Harry to laugh way too hard that his face went red.
Lily now looked looked like a grandmama,she had white hair.
"What's so funny?"
"Look at your self,you are old!"he exclaimed.
"Am I?"
"Oh yes you are!"
After becoming her 11 year old self lily continued trying another ten wands till she found hers:Unicorn hair,10 inches long.
The twins paid and left to buy books and cauldrons for their potions lessons.
Hagrid was waiting for them outside the potions shop.
Lily was trying to reach a large book atop a high shelf so she stood on her toes and tried reaching it.
All the books would have fallen on top of her,if it wasn't for,Snape-Severus Snape.
