Ok...mine are pretty sad, but here they are anyway
One time during my freshman year of HS I was running a cross country race and I had to pee SO badly but I didn't go before the race. Well I was running and I just HAD to go, so I peed my pants while I ran. It was so sick, but I knew my coach would have KILLED me if I just quit running. It was difficult to explian to my mama afterward though what had happened.
Another time in the 8th grade we had a tarantula in our science class. I went to a small school and my whole class knew how scared of spiders I was. Well one day during a free day some kid was playing with it and he set it on my shoulder and then tapped it so I would look. I screamed so loud and peed all over my chair and I had to go home in the middle of the day to change.
The last one happened last semester actually. It was really cold out and i was all bundled up in my bed in a deep sleep and in my dream I was peeing. But wow, I guess I was in real life too b/c I woke up and I had wet the bed. At age 19! And I hadn't even been drunk.
Sadly enough I have even more pee stories, but I will end them here.
