Hopefully you don't have a cat who goes near your gaming area.

I love my fuzzy buddies, but every now and then one of them steps on the keyboard while I'm doing something and I see that flash indicating a key that did something got pressed and then I start panicking because often I can't tell just exactly what it was ... if it was something gravely important, especially if it was some random option that I'd never even have thought about in a million years and therefore would have no idea how to reverse!
