BAD Attitude!

So anyway! I have a horrible attitude about things today! With it being the end of the semester, the kids don't care, which I have decided I don't care anymore either. I have one meeting after another, when I have things to do. I know this is my problem, but I live 30 miles from where I work, & I didn't get home last night until 8 PM b/c of an "open house" we had at school last night. How come it's the kids who give you behavior problems in class that can ruin your whole attitude about the whole group? Isn't that horrible? I have some REALLY sweet kids, but it seems the "bad" ones outnumber the ones who really want to get an education. I have decided that after Christmas holidays, I am going to start treating them like they are in highschool. They might as well get ready for it. These kids just want you to "spoon feed" them. They don't want to do anything for themselves. They want to sit & get grades for it, passing grades at that! I will NEVER understand the mentality these kids have! This is really ruining my "Christmas spirit" HELP!!!!!!
