On the up side, fewer bugs

I was talking to my mom on the phone tonight when I looked out my window and saw three BATS zipping around! My windows open like doors, and as we've discussed, have no screens. So I closed them for a while but it's so hot, wah wah wah, so now I have them open but with the curtain over it so that a bat's echolocation will ping and tell them not to go there.
