Geckos vs. Cockroaches

As I sit here writing, there's a small gecko climbing up the computer next to me, which is making me wonder: why are geckos "cute" and cockroaches "ugly"? Not that this is one of the great questions of the universe or anything, but we've encountered plenty of both species here (OK, the truth is that we've each stepped on one- don't tell PETA), and the geckos always seem so much nicer and friendlier. Can geckos even be friendly? Anyway, I've given this subject the five minutes it deserves, and now I'm going to go write about something else, like Thai hookers.
