So I left the top part of a window open last night, not realizing that it only had a half screen on the bottom.

I woke up at 4 a.m. to a scrabbling sound. Normally in my house that means a mouse, and that freaks me out, because IMO there are not many things more disgusting than a mouse running across my sleeping face.

I turned on the bedside lamp, which would normally cause a mouse to freeze, but the scrabbling continued. Then I realized where it was coming from ...

Poor bat couldn't find her way out even though the window was wide open. She was flying in circles around the bedroom, obviously getting tired, stopping to rest on the ceiling fan for a few seconds but not nearly long enough for me to think about herding her or throwing anything over her. I eventually just opened the screen in the adjoining bathroom and waited for the bat to fly in there, then closed the door, put a bedsheet across the crack at the bottom of the door, and went back to sleep.

Before I opened the doors wide this morning I made sure to check the lamps, shower curtain, edges of the medicine cabinet, everywhere I thought a bat could hide. Apparently she found her way out.
