Not a mystery hunt post
Lessons of the day (and it's not even 11:00 yet!):
1) Those full-height subway turnstiles will sometimes jam, even if you swiped your card and it said Go, and even if the person in front of you went through fine.
2) Those full-height subway turnstiles have a spoke right at the height of my mouth.
3) My dentist's office is not open on Wednesdays.
(It's just a couple of small chips, and there doesn't seem to be any pain (yet), but still, it sure feels funny.)
