The Senior Instructor at the karate school had some molars pulled so Mom taught the Black Belt Class Monday, Tuesday and last night. On Monday she helped with two classes after that and on Tuesday she helped with the Black Belt class. So Mom's a little tired. She is taking class tonight and then will have no karate tomorrow (hopefully).
Believe it or not, it's tiring talking for 45 minutes straight to 20 something students as you teach them how to swing sticks, avoid knives and punch people all while running around the mat making certain everyone is doing well.
No wonder she's tired.
