We left the bedroom window open last night. It was so nice to start drifting off to sleep with a gentle breeze caressing my face, with the nice night smell... and then right before I fell asleep the upstairs neighbors came out on their landing and I could hear clear as day what they were talking about. Two girls with little ugly giggles and two guys with big ugly guffaws. Thanks a lot. So I turned on the fan and luckily it helped a lot. Cory didn't even wake up, which surprised me.
