Input: Text: so this story actually happened about two years ago and isn't really a big fuck up or anything but it's still something i get teased about from time to time by the friends i've told the story to. anyway here's the story.  
  
i had been hanging out with a friend at her dorm but had to leave for class. as i walked towards the area where the elevators and stairs were i noticed two or three really attractive girls waiting for the elevator. i didn't think much of it and started making my way towards the stairs. as i was about to open the door to the stairwell i hear one of the girls call out to me and say "hey the elevator is here". i turn around and see them holding the door open for me. i stared at them for a second or two and just said "but i like stairs". the girls obviously weren't expecting me to say that and they just stared at me for a few seconds while still holding the elevator door open. i then turned around and began to take the stairs. as i was half way through the second flight i realized what i had done. i always wondered if i had taken that elevator maybe i would have befriended those girls or dated one of them or something. then again i'm pretty sure they were out of my league but oh well.
