I think I am just too…

I think I am just too tired to go to my drawing class tonight. (The teacher had to cancel this morning's class, so invited us to make up the time at his evening session.) Am bummed, and feel a little silly, since I have paid good money for this, and it is supposed to be a fun treat, but am also trying to be reasonable; am still healing, and rest is important. If I have to drag myself there, then it is clearly not fun, or a treat.
