Input: Text: last night i had been out at a concert with a few friends when we saw two rather attractive girls wearing matching hats. after drunkenly shouting the innovative pick-up line "hey i like your hats", the girls came and talked to us and we hit it off with them, with much hat-related banter. 

eventually, the hat compliments must have paid off because they agreed to come back to my friend's apartment for some drinks. on the way back to the apartment i had a good conversation with one of the hat-wearing girls and things were looking good with a high likelihood of a hookup later on. 

anyway, we made it back to the apartment and after a few more drinks, things continued to go smoothly and the outlook was looking good. 

that was until the girl i had been talking to asked me to get her a glass of water. as i walked to the kitchen to get said glass, i stumbled around a corner and spontaneously dislocated my left knee, falling to the ground and yelling out in agony. have never done this before and it was kind of a freak accident. 
anyway, the girl was very nice about it and comforted me as we waited for an ambulance, but was undoubtedly put off by my disfigured knee, profuse sweating and grimacing, constipated-looking face as i attempted to hold back tears - am not expecting to hear from her again :/
