In Chinese, they call geckos 壁虎 (bi hu, ㄅㄧˋ ㄏㄨˇ), which literally means "wall tiger."
Troy is not my first "wall tiger" guest. When I lived in Meinong, a gecko with no tail stayed with me for a very long time. I called "her" Margo. :)
You might know this already, but most geckos have no eyelids and instead lick a transparent membrane which covers each eye.
And, I didn't ask Margo and haven't asked Troy to leave. Why? They eat insects. And, well, they don't speak English or Chinese, and they move fast!! (I suppose snakes could fit into the category too huh? But, I'd make sure they weren't welcome. So, uh, I guess I also let Troy and Margo stay because they are harmless.)
I think Margo stayed inside most of the time, but Troy likes to come and go. He disappears over the front door whenever I try to get too close.
So, have you ever had your very own house gecko?
