Thus, it was not until Gretchen went to hang up the shirts in my closet tonight that the problem was found. The long shelf in my closet had fallen off the wall, making it nearly impossible to open the door.
We have now piled all of my shirts and the contents of the shelf elsewhere. And I need to figure out the best way to fix this, because things are pretty much an unholy mess.
Apparently, I have too much stuff.
