Frustrating day

Today was one of those just plain frustrating days. I woke up grumpy because I didn't get much sleep. I think I may have dozed off for a total of 2 hours throughout the night. I just couldn't seem to fall asleep. I got up and went to the school. I tried getting a Mountain Dew before class but the machine gave me a diet which tasted HORRIBLE. (If you didn't notice, I HATE diet soda.) Anyways, my speech class went ok. We watched some famous speeches and I fought to stay awake. When class was let out early, I went over to the library to work on getting ahead in my math class. For a while it was nice and quiet except for a girl talking loudly on the phone. A short while later, the guy she was talking to decided to come see her. He was talking SO loud. It was like he was trying to talk over some voice that only he could here. Then he started walking around asking people why they were studying. I wanted to yell at him, "Because we're in the library. What else are we supposed to be doing? Throwing a kegger?" I got sick of it and left. I sat outside my class room for an hour before it started. I got some reading done though. Then in my English class, things got worse. First a girl was complaining because last Thursday we were told (in joking) that he might give those of us that showed up extra credit. She was upset because she didn't show up and she didn't think it was fair that those of us that are willing to show up every day might get some extra points for doing so. Then in class we went over grammar errors. Most of the things we went over, were things we learned in middle school. Somehow, so many people had completely forgotten those things. I started getting so tired of it all. They were simple mistakes like changing a comma into a period. When I got home I started yelling about how ignorant people are. I was so angry. I don't even know why I was that angry. I just got furious. Then when Zach got ready to head to a meeting, I decided to take a nap. I had some kind of nightmare and woke up a couple hours later. I was still angry but not as angry, though I did feel really crummy from my nap. Zach went to his tutoring and I went to my math class which made me almost as angry as my English class. I understand that I'm in a remedial math class but people in there are just . . . I don't even know what to say. Simple things like learning to change the less that sign to a greater than sign when multiplying or dividing by a negative number was so hard for them. They couldn't just accept that you change the sign when you multiply or divide by a negative number. They had to ask why. Then if the variable would always be greater than a number. (I have NO idea where they got that one.) Then when we were talking about set notation  { x | x<9 } they couldn't accept that you put the condition in the second part. They had to ask so many questions. Why can't people just accept something that will ALWAYS work. They need to know all these things that just confuse them even more and mess them up on the test. Anyways. I'm home now trying to relax. I want to sleep but I feel so jittery. I want to do something but I can't think of what to do.
