So, DH is back to college full time.
He was sitting in one of the halls on a break, waiting for class to start. He said he was reading homework, so wasn't really keeping track of the time. He noticed students scurrying into class late and thought, Crap! I'm late to class, so goes barreling in after them.
To the wrong class. He's embarrassed now and doesn't want to get up and walk out, so he stays in the class.
All the way through their group project of the day.
I still can't believe he sat through an hour long class and a group project. I laughed and laughed at him.
