My first 14 years teaching was  in St. Michael's High School GFW, an all boys school, run by the Christian Brothers. In 1982, St Catherine's girls High School amalamated with our school and the teachers from both schools began teaching boys and girls but in separate classes. Of course during my first day of teaching girls I was rather nervous in my new surroundings. In those days you were required to wear dress pants, a dress shirt and tie as well as a sports jacket. When I entered the classroom there was complete silence, as I can imagine that they were as nervous as I was. When I went to the blackboard I picked up a stick of chalk to write my name as was the custom. As I reached up to the top of the board I dr0pped the chalk and stooped down to pick it up from the floor. When I did, the back seam of my pants ripped open. Noone laughed. Red faced,I turned around and asked them to read a number of pages in the book from the democracy course 2102. I left the class, went to the home economics room and asked the teacher for a needle and thread. I also borrowed a chair went to the boys washroom, took off the pants and sewed the seam back together. ( I grew up in a family of 14). When I returned to the classroom, the girls were still reading. I wonder would that happen today! I retired in 1998. That was one of my most embarrassing moments.
