Try to hold it

You decide you should go to class first and then ask your teacher to go. It's the last day so there shouldn't be a issue. On your way to the classroom you are stopped by the Vice Principal. She has always been a ball buster and it seems like the last day of school will be no different. "On time means on time every day. Even the last day." She lectures you as you squirm. You try to interrupt, but she is having none of it. Then it's too late. You stand there in horror as your bladder empties into your jeans.
