If you're bored and like guessing games, try the
Petals Around the Rose puzzle. Some people get it almost immediately, but if you're like me you'll waste substantial amounts of supervision work-time getting frustrated at it instead. Don't worry, I've worked it out now. But you're not safe yet. :P
In other news, I have an infestation of cockroach. It was so huge that when I first spotted it I couldn't think straight and shut it in a drawer, but by the time I'd armed myself with a plastic box it was no longer in there. *shudder* Maybe I should set the college cat after it.
