I permanently lost a binder of physical therapy exercises that I had spent 2 hours collating and organizing by body part, with tabbed divider pages. In a 785 square foot 1 bedroom apartment. I suspect I accidentally dumped it in a bag of stuff to donate to the local thrift store. Someone got a great resource for the price of a used binder.

I have recently done several things I have no actual memory of doing: putting the sun shield in my car window. I just now forget the other thing I forgot. It's maddening.
