I called #3 Son at about 8:30pm, thinking he would have been out of class for some time.
Him: You obviously don't have my schedule.
Me: Why? What?
Him: Because if you did, you'd see I'm scheduled to be in class until 10:00pm.
Me: Okay. So why aren't you in class?
Him: Because lectures are shorter - this is a hybrid class, not a jumbo.
Me: ??? (Or, in language we can all understand ... WTF?)
I guess I've been out of school WAY too long.
