Yeah, I fail pretty hard.
I had planned to call the doctor's office this morning to see if they needed me to obtain an alternate form of the MRI results. When I did, I looked at the appointment card to see what time my appointment was on Thursday. Much to my surprise the appointment is actually tomorrow, Tuesday, at 4:15.
Maybe I should have looked at the card sooner, eh? Good thing I did look at it though, because I would have let it slip by without any thought.
