My upstairs neighbors inadvertently woke me up when one roommate knocked on the door to the master bedroom upstairs at 3:00 AM. The way these condos are built, noise reverberates in every direction. Once I'm up, I can't fall asleep again for several hours. I get up and start quietly puttering so I can keep my mind and hands occupied until I can go back to bed later on.
As the dawn light makes more things outside visible, I spotted a young possum walking by the fence. I'm halfway expecting one of my neighbors to throw a hissy-fit screaming about a "rat" because they're city-folk and not comfortable with wildlife like possums, foxes, deer, beavers, muskrats, herons, hawks, cormorants, etc. So far, (knock on wood), I haven't heard any screaming hissy-fits yet.
