Allo, allo!

I went out last night with a few of my mates to a sort of school reunion at this club. Anyways, I was doing really well with body language, social proof and whatnot.

Later on, near the end of the night, I was a little tipsy but this gal kept giving me IOIs, but I totally flopped with AA. I said hello, span her round and then blanked. When everyone was leaving I said hello again and we exchanged names but her damn friend pulled her away.

MY QUESTION: It's unlikely I'll see her out again, and since I don't have her number I thought I'd add her on facebook.

Does anyone have any advice on how I should message her when I add her?

Cheers!
