Isn't "Let off -" the beginning part of implying that you have passed gas?
Hmm...
School lets you off
you are a fart.
every morning School sucks farts in and then lets them out in the afternoon.
school teaches you how to be a better fart
other farts are mean to you at school.
if you get sick school lets you off early.
If you're sick school doesn't suck you in at all.
you are exchanged in between 3 schools and/or more.
Education to adulthood is the longest lasting fart research ever.
This entire reply is a brainfart of some handicap with a bad sense of humor.
