I'm a weirdy. I loved high school. I love college. Heck, I even loved middle school/junior high. ...Especially in retrospect.
...But seriously. I really have enjoyed the majority of my educational career. The social aspect of high school was awesome, and in college it just goes to a whole new level. Sometimes it sucks, but that's okay. It's all learning experiences, if you let it be. Besides which, I know I wouldn't recognize all the fantastic times I've had if I hadn't had those miserable ones.
