A childhood belief about teachers

I used to think that teachers were really the morally upstanding people that they pretend to be during class. I thought teachers did no wrong. So one day when I was in the grocery store and encountered my 4th grade teacher, with husband, in a bad mood I had the shock of my life. She obviously was having a fight with him or on pms. Anyway, my mom in I were in the frozen section and my teach and her man were looking at some meat. Mom told me to go say hello. I didn't really want to but started that way. when I got close to them I heard my teach say "I'm tired of this shit!" to her man. I froze and then ran back to my mom. I thought my teacher must have been beamed up by aliens and had her brain sucked out and replaced with a alien brain because no teacher would ever cuss. They always said cussing was wrong! the next day I was very scared in school because I thought the alien brained teacher was going to recognize me from the grocery store and realize they had been found out. She never said anything to me though. I now think that she was too mad and focused on what she was telling her husband to have even realized I was in the store. Either that or embaressed I was there. It wasn't until I was older that I realized teachers aren't morally perfect people but just regular peeps who try to put on a good act around small children.
