There were a lot of teachers that were married, and that in itself didn't make sense to me. Not because I thought they lived at school, but because they had such awful attitudes that I couldn't imagine somebody agreeing to spend their entire lives with them.
Then I grew up and realized that their husbands were probably awful, too. Either that, or the teachers took all their frustrations out on their students and had happier home lives. Either way, I still find it pretty sad. I know patience is a virtue, but you should know what you're getting into when you choose to become a teacher. Shitty teachers create traumatized students. If you don't think you can hack it, please, for the sake of all that is good, consider a different career.
