I don't mind them at all, and in many cases, they can be pretty helpful. Sure, they kind of hang out all over the place and where you least suspect it, but without them, the amount of nasty bugs and insects we'd have would be way worse than it is now.

Sometimes it's fun to tease them. They could be sitting there completely motionless for HOURS, but give them just the slightest of pokes and they'll go into full crazy scramble mode and will dash around at pretty crazy speeds.
