How to impress a friend of my elder sister?

[mayankisawesome]

I have a crush on my sister's friend.
The only connection i got with my crush is Facebook.
She has way too many male friends on fb.
What can i do to impress her or first be friends.
I mean how should i start the conversation with her on chat.
i don't want my sister to know anything about it.

Okay my man first thing you need to know is your sister is gonna find out, there is no way to avoid this. Stop worrying about her male friends on Facebook "how many times do you see her during a whole week?" I'm assuming that she already knows you cause she is friends with your sister just try a simple "Hey" that will start a conversation up and try to hold on to the conversation.

a friend of elder sister is also a girl.. all rules of others girls imply, and if you genuinely like her then why dont you tell your sister... she is gonna find out anyway.
