What day is it?

Woke up early this morning preparing for a full day of appointments when suddenly at 8:30 a.m. I realized IT'S WEDNESDAY, not Thursday. I'm supposed to be at the dentist, not those other appointments. I called the dentist. "Can you still take me if I hurry over?" (A 20-minute drive away) "Oh, your appointment isn't until 9:30 a.m. You still have plenty of time."

I think I'm losing my mind. But at least I gained a whole day!
