Good for you. I would have held it in like a wuss.
I had no choice, I had to go badly and I had a fairly weak bladder at the time. I actually did hold it in as long as I could as I recall. The teacher was a b.i.t.c.h and should not have been teaching.
In the 80s, we still used the English style schooling system, which included corporal punishment, featuring canes, leather straps and other fun measures.
Yeah, I went to school in the '70s mostly. We used to go to the principals office and he would just tap this thick leather strap on his hand while talking to you and that was often enough to scare you into submission. The really bad students got it, but it was rare as most didn't do anything bad enough to warrant it.
I hated school growing up. Not because I didn't like learning, I loved that, but due to bullies. At one point I would skip school and go to the public library and spend most of the day there reading about radio electronics and eventually, when computers came out, I started reading books on programming them. For this reason I am a strong advocate of home schooling.
