Should i do it or not?

[allen]

I recently started using Facebook again ( i stopped using it in 2009) anyway, In my old high school i knew a chick i was friends with her until i changed school this year so it has been months since we last saw each other, anyway i want to add her on facebook but i'm afraid she won't recognise me. but we were great friends. I'm also considering changing my profile picture before i add her because i'm wearing shades so she might find it hard to recognise me.

we have mutual friends but long story short i'm afraid she forgot me after about 8 months of not talking to each other! And if i added her and she accepted how do i start a conversation without being awkward or getting the FAMOUS "do i know u?" question. so i also need a conversation starter.
