Worst case scenario:

[black_solstice]

You are in the bathroom, in a towel, in the middle of the night, and there is a huge cockroach with you.

When you finally run out to get a slipper, it disappears.

THIS IS ME, RIGHT NOW.

Update:
I have successfully taken a shower. However, the cockroach still lives. I believe it is mocking me from wherever it hides.
