Two-Parter

I typically watch an episode of Star Trek while using the treadmill and most of my family has gotten used to the 42 minute block of thunder from upstairs.  Today, after about 55 minutes, my dad checked on me to make sure I was okay, he looked relieved that I wasn’t being sanded by the belt but also confused.  I looked at him as said “two-parter” and the confusion lifted.
