In The Spring of 1989 I took a class, I forget what the actual name and course # was but the gist was that it was the course where education majors got their pre-student teaching experience. Over the course of the semester you travel to a school, are assigned a teacher and a class room and you observe and assist in the class room culminating in preparing and giving a lesson essentially being teacher for a day. I forgot how many visits it was it was either 6 0r 12 in a 6 week period.
I got to know the students pretty well, and one of them was going to be in a local theater play. I told him that I would attend. Back than my wardrobe was pretty exclusively jeans t-shirts and I had a pretty good sweater collection. I had one suit and a few dress shirts and a couple pairs of slacks. Each day I would go to school, I would wear the same outfit, my suit. I would then go back to the dorm and put it away until the next class. When I went to the play I was wearing my regular out fit of Jeans, Turtle Neck and Sweater.
The play was really good. It was Agatha Christies Mouse Trap and my student did an excellent job. I went up to him after the show and the first thing this kid (who by my math is now 50ish) says to me: "Mr. Roller, You're in civilian clothes!"
I was thinking of that story today, because my youngest daughter has a starring part in her school play. I wore Jeans and the show t.shirt to school today and wore the same thing to the production. I don't think I've ever worn a suit to teach school. I guess I just wear civilian clothes.
