I am dead tired. Not sure why, exactly.

I am dead tired.  Not sure why, exactly.  I only got up early, took a big, heavy dog to the vet by myself, came home and washed her, cleaned Booka's stinky ear, did some literature, made some food, drove 45 minutes, sat through 2.5 hours of Calculus, and drove another 45 minutes...  😜

If my phone doesn't hurry up and finish charging so I can go to bed...  🙄😴
