I was out drinking with some friends last night and my buddy introduced me this older man and his daughter (HB8). Now I swear I've seen this girl before but I couldn't place her. I talked to her for a bit but we ended up leaving and going to another bar. Apparently my buddy invited them to come to the new bar we were at, where they showed up a bit later. I was outside with a plate of mine and my buddy just shooting the shit. I left a bit early, leaving my plate and my buddy at the bar. Apparently after I left, this girl came out and say with my buddy and my plate and was going on about how hot I am, how im just her type, and how I drive her crazy. She also said that I've hung out with her before, which is possible that I did one night drunk and don't remember. Anyway, after hearing all this from my plate, i friended this girl on Facebook. My question is, how do I initiate a conversation with her? I don't have her number, just messenger. I could just go direct and ask her out for a beer or I could strike up a conversation on where do I know you from. Thoughts?
