Why do teachers who obviously do not enjoy being around children choose a profession surrounding kids?

Oh I have had many of those. But I don't think they started out that way. I think there was a time they loved working with kids but over the years between the administration and the kids that just don't listen and parents that don't care they started hating what they do. Now they could always quit but some can't afford to start over and are counting on retirement.

I went to a small university that was known as a "teacher's college". Most of the students didn't know what to do with their lives so by teaching they could just stay in school. As the old saying goes, "Those who can, do. Those who can't, teach."

it was a noble thought when in their 20's taking courses in college
and now after years of work, crappy bosses, disrespectful children and parents
just guess what happens!

@prettylittleliar: Are the teachers you describe older or younger? Take into account how underappreciated/underpaid teachers are. It's one of the most important jobs on the planet, yet one of the most underpaid and underappreciated. If you're a teacher, that can really wear you down over time. For example, Mrs. Johnson began her career as a fantastic teacher and gradually, her abilities (for lack of a better word) slipped down to that in your original post.

Because they couldn't hack it in the real world.

my math teacher hates me and is really mean. theres more mean teachers than nice too

They had different expectations or got into something just because
