Oh man, I can imagine! I had been hunched over a table, talking to a friend who was running a booth, and we were discussing plans that had gotten screwed up, so my voice was really low and I guess I must have had an urgent, upset expression on my face. After I'd staggered away, a hotel worker came over and asked if she should call me an ambulance. *facepalms*
It was funny, awesome, and a little sad at the same time. funny because... well, it was just a costume. Awesome, because clearly the makeup looked great! A little sad because... it was all done with whatever eyeshadow was lying around, so I glittered in the sunlight, and some people still couldn't tell it was makeup.
