Congrats on your first day teaching, laphtiya. Sounds like you had a pretty well rounded experience.
My father was a teacher (just retired last year). It's one tough gig and doesn't pay well. So you really have to want to be a teacher. I'm sure you'll do well at it as you grow and learn in the process of teaching. Yes, the teacher is constantly learning as well.
My Dad got out of it when he did because he was doing a lot more babysitting and disciplining in the later years that he was teaching. Each new class was more misbehaved that the last, the school's politics and angry parents who just wanted their kids passed regardless of their accomplishments (or lack there of) really made him hate his job. He told many nasty stories and I can't blame him for getting out when he did. I wouldn't have lasted as long to be honest!
I sure hope the students (AND their parents) are better behaved where you are than they are around these parts.
Good luck to you.
