I can't believe I just pooped my pants while driving my car.
That's horrible. Why did you poop your pants while driving your car?
I ate some bad tacos.
That is really embarrassing to do that. But it couldn't be helped, so don't feel bad.
I really had no choice after eating those tacos.
I am sorry that you poop your pants while driving. It is okay to be embarrass about having an accident, everybody has accidents.
