1 am Blackout

So, it's never a good sign when you find random texts on your phone from the night before from a number you don't recognize. Especially when you ask who it is and the reply is "the guy you made out with last night." You're kidding, right? How do I manage to remember the beginning and the end of the evening with complete clarity but blackout for the 1 am makeout session? It doesn't help when your girlfriends are equally confused as to what led the chain of events to occur....I just wish someone would tell me if he was hot or not.
