I thought it was treat others the way you wanted to be treated

As I was growing up my parents always told me to respect and adult because it is an good thing to do, so i do as I was told. Well once I got to High School I found out that most of the teacher here have respect for students as long as the student respected them, but there is a few teachers that just get attitudes with students that actually show them respect over one little simple they could easily say i'm not answering it or tell them the answer they don't have to get an attitude over it. I mean i know they are stressed and stuff but that doesn't mean to get mad about it and take it out on students that actually care about there grade and etc. I know there is some people that don't believe in God but the people that do know there is something called the Bible and in there its say treat others the way you wanna be treated and I think the students that show respect should get respect back instead of getting and attitude from a teacher.
