During my elementary school years, call it naive, but I thought everyone wore diapers. I knew them as underwear and wasn't any wiser. It wasn't until I was being changed in the community center bathroom and a little kid (younger than me by a year or so at the time) was using the urinal and I saw his underwear and realized that he wasn't wearing what I was wearing. It probably wasn't until third grade that it dawned on me that my mom was dropping off diapers to the school nurse a couple of packs a week and I was one of only two or three others that where being sent to the nurses office every few hours. It was in 3rd grade that I really knew something was different and I had the talk with my mother about me being in diapers and she knew shortly after my birth that incontinence was very very certain. I don't really remember being teased for it then but probably from 5th grade on the bullying started.
In middle school I really only have one memory of a girl who had accidents from time to time (rare) and we passed each other in the office one day. I was observant enough to notice that when I had made my earlier visit there was one diaper left in my open pack and then when it was my turn to go in the back room I was given a diaper from my brand new pack. It sticks out in my mind because I remember the nurse having to open the new pack before she got me one. I could only assume that Viola (the other student) had been given the last diaper out of my open pack. I vaguely remember as well seeing store plastic bags of spare clothes with other students names on them that was usually sweat pants and underwear but maybe 5 out of the 10 bags you could identify a single goodnite style pull up. My guess is I wasn't the only one who where dealing with issues but I probably was the only one in diapers full time since I didn't see any other packs of diapers that weren't mine.
Middle school got progressively worse in the bullying, name calling, teasing, pantsing (not particularity sure what that was a favorite of some bullies) department, high school even worse than middle, but for some reason in senior year of high school the name calling and bullying and just sort of stopped like everyone had better things to worry about. It seemed it went from being teased by everyone to just a handful of people.
I didn't really participate in a high school sports and during gym class in HS they usually would let me do extra school work or study. In middle school the called it PE but I went to a classroom instead of the gym with a much smaller group of kids who were differently abled. That group never had made a visit to a locker room and it was usually you could put gym shorts on in the bathroom that was in the classroom. No swim team here for obvious reasons. But yeah, elementary I was dumb and didn't know any better, middle school was horrible, high school seemed to get better.
