Take a piss

You really begin to wonder if you should go take care of your needs before you go to the principal's office. As you keep walking the need gets more and more intense until finally it takes care of itself as your bladder control fails completely and permanently. As your piss continues to flow, your underwear becomes the diaper you have worn since you were born. Your clothes slowly cease to have ever existed since you are not a big boy because big boys are potty trained. Big boys also know how to walk which is why you never learned to walk.
