Why?

How

So after the party ended, all my friends started questioning me.......Kon tha wo?? Tumhara boyfrnd tha......oooooo
Relationship me kab ayi tum?? He was so handsome?? Naam kya hai atleast ye to btao.....kaha rehta hai uska koi aur bhai hai kya?? Kaha mile tum log kab mile??

And I didn't knew what to answer.....All I said them was "I don't know him".
And they didn't believe me and kept on questioning so I had to unwillingly say them that "Yes, he is my boyfriend and his name is Rehan and I want to keep it private so stop questioning me"

They were shocked to hear those words before they could ask anymore questions I held my sisters hand and said "Happy Birthday, I forgot to bring your gift it's at home so let's go back and the restaurant will close down soon too. So, bye guys let's meet tomorrow" and I left the restaurant. My sister followed me after having a proper farewell with them cause she was going abroad for her further studies she wanted to spend some more time with them specially with Ali cause they were quite good friends and maybe something more than friends but we never talked about it cause I knew she won't tell me and she knew that I won't let it stay and the very next day it might get published in the newspaper ( But I wasn't of that sort who couldn't keep things upto her,maybe).

We came back home, my sister got busy with her packing, she had to leave early in the morning. It was midnight when we were having our coffee and busy with our thoughts and fantasies and girls talk. Suddenly a questioned poped up in my mind that how come Rehan got to know my name....... Yes, before leaving he said..... "It was fun to be a part of your party "Mashal" I hope we will meet again soon"
At that time I didn't realised but I never told him my name. I was busy with these thoughts of mine when I realised that my sister was looking at me with those suspicions eyes. I asked her "what's wrong why are you looking at me in that way".
She said that she was trying to read my thoughts through my eyes. (Isn't that weird how can someone read ones mind through their eyes, lol)
I said her what I was thinking about than she said " Silly girl, he might have heard your name in the party obviously if you don't know him than how come will he get to know about your name btw you said that he's your boyfriend than how come now you're saying that you don't know him"

So,I said her the whole incident how we met and because everyone kept questioning I had to say that he's my boyfriend just to stop their questions.
She started laughing and went back to her room saying "He was a good looking guy though, you must date him if you meet again"

Aur mujhe sach me samajh nahi aya usne kaha kya......agar main usse dubara mili to date q karu.....kya good looks kaafi hote hain kisi ko date karne ke liye???
Party mein to kisine mujhe "Mashal" nahi bula ya....sab mujhe "Mishi" bulate hain.......use mera naam kese maloom hua?? How??
