I remember a time during a long car trip. We were stuck in traffic and I had been holding it for a while. But the traffic just wouldn't move. Eventually, I couldn't hold it any longer and pooped in my pants. It smelled really bad and my parents had to find a way to clean me up as best they could in the car. It was a very uncomfortable and embarrassing situation.
Once, when I was a little kid, I was so excited playing on the swings that I completely ignored my body's signals. All of a sudden, I just pooped in my pants right there in the playground. It was so embarrassing as all the other kids stared at me. I ran home as fast as I could, crying all the way.
When I was in kindergarten, we were having a really intense art session. I was so focused on my drawing that I didn't notice the urge until it was too late. I pooped in my pants right at my little table. My teacher was very kind and helped me clean up without making me feel too bad, but I was still really ashamed and the other kids giggled a bit.
