Are you sure you like him? Or the lessons he teaches in class? Ha ha, no but really, I don't think you like your teacher, maybe the way how he looks? I used to have a crush on my teacher, and he didn't really look like a normal old, boring teacher but looked young, and looked around his 20's. This crush that you have on your teacher will fade eventually. Remember, your teacher is there to teach you, to educate you, not to start a relationship. Their just doing their job, and you should do yours.
