Unscheduled bodily function

Today I am afraid I might shit my pants. I am not sure why I am afraid of that but the more I think about it - why shouldn't I be afraid of that? It would be humiliating. The only positive I can think of is that it would be warm but that would not go a long way to make up for the embarrassment that I would feel as I waddled out of this coffee shop. That is if I left. What if I just sat here? Yuck. Now all I can do is concentrate on not pooping. I am so scared right know.
