My mom has a dentist appointment around 11:30, so I may be a half-hour late. Is that okay?
Scratch that. The appointment is at 12, and it's a half-hour long. Then I have to go to Target, so that should be another 50 minutes to drive there, shop, and drive home from the dentist. I maybe anywhere from a half-hour to an hour and a half late. I hope that's not a problem.
