Why have I been so tired?

My mom called me yesterday afternoon and told me she was going to be in town today and tomorrow and to see if I wanted to do dinner with her. Luckily, I dont have anything that i have to do. I am supposed to go to my students football game tonight, but I think it will be okay if I miss it. My mom isnt in town that often. I remember quite a few months ago, she told me she was coming down for a convention with her work, but she didnt know exactly when. I guess that its today.. lol. I am not sure where we will go for dinner, but it doesnt really matter. Dinner is dinner. Otherwise, Im not going to do much today after work. Hopefully go to bed early. I have been so tired lately. My roommate has been too. Actually, a lot of people have been. I am not sure what is going on. At least it is Wednesday - that means my week is almost done. Luckily I do not have much planned for this coming weekend. On Saturday I am doing lunch with my friend Katie. Then, I have Dave's hockey game and after that a group of us are going to go to a comedy club. Nothing too draining. Well, i need to get to work and get stuff ready for the students - they should be coming in a few minutes.
