Need to clarify my statement about leaving early. If you have to leave for band or family emergency or anything related to urgency for your family or religion I don’t have a problem with that. I understand I have a bunch of band kids that have to get to the practice and performances, I am the guy who is flexible to all other school based activities. Sorry I didn’t clarify this. I was talking to the people who really don’t have to leave before the cool down.
