Did
Get to hear my favorite busker on the subway
Decide that I would rather make models than do boring stuff
Make models most of the day
Watch Underling get fired
Pretend not to see someone on the train who then waited for me when we got off
Finally get to go back to the gym

Didn't
Prep the terrible presentation I'll eventually have to give
Follow up about that raise
Worry about finding a new job
Speed squat very speedily
Seize the interesting conversational leads dangled in front of me
Get too angsty about it
