Have you guys ever been in class but needed go to the bathroom and pee really bad?

The thought are going crazy in your head:
Don't think about how much you need to pee, just think of dry stuff.
Not waterfalls, or foutains, lakes, the sea or anything that has to do with the colour yellow.
come on get a grip! I know you can do it.
I can't!
Yes you can!
No, I'm sorry, dude, I have to pee.
not in the classroom!
I'm sorry....
