It's 2 a.m. Why do I hear a bird chirping outside? Wait, maybe it's a bat. Ewww. Yuck. Do they really have bats around here? What else could it be? Bats stay up all night, I think. What if I was a bat? I could fly everywhere. That sounds like fun. Then again, I'd have to live in a cave. But there aren't any caves around here. Great. I'll end up being a homeless bat flying in the air making noise all night and getting people who aren't sleeping to think about me. Maybe it's really a bird. I should Google birds that chirp at night.
