Today I went to work as usual. I started working on the first patient when I realized the other hygienist had come in, but there was only one column scheduled. No one said anything. Half an hour later I realized I wasn't even supposed to BE there (it wasn't my name on the schedule) and still no one had said anything! Luckily my dentist had hygiene patients scheduled the other hygienist took over. A few hours later I vaguely remembered agreeing not to come in today. I literally stole her patients. April Fools' to myself, I guess!
(yes, this is a true story!)
