When I was in high school I seemed to always need to go toilet just as the period started. The teacher wouldn't let me out the first time I asked because he says I could have just gone and would have to wait until later because the class is starting and he doesn't want me to miss out on anything. The second time I ask he says it's too close to the end of the period and I might as well wait until it's over. It was pretty horrible and I always thought I was going to pee my pants. I never did, thankfully. I had to cross my legs so tight I started to ache in my hips and back. Sometimes when the bell rang, though, I swear I almost wet myself in excitement. It wasn't so bad in the 1 hour blocks, but the 2-hour science blocks I had in Year 10 were gutbusting.
