Picked this one up through your LJ...
I like it. Good little short story, and it definately drew me in. I really, really enjoyed it, and that's not something I can say of many short stories, since I generally don't enjoy the format much.
I also liked the twist with the end, though I personally would have adjusted the scene with Sam in the washroom a bit to make his thoughts a bit more clear on his true position. Not enough to give everything away, but enough to hint at it a bit. Just a suggestion, though.

hey elise!!
i just picked one of the stories from the list in your journal and decided to read it, and this one is amazing :D :D
When i was reading and it got to the part where Colin was asking where's justin.. i was like who the hell is justin? but then i love how you explained it all at the end. i didn't see it coming.
very charged story, made me wanna keep reading.
good work :) i think that this would be awesome to submit in a contest.
