We have this old sub dude. He's prolly late 60's. But he definitly has a hearing problem so he catches nothing. And if he does catch something he doesn't like, he wastes like over half the class (no joke), telling as stories about old schools in the north end he taught at, and how he listens to the news all the time, and how we should be more respectful, and how young kids are getting worse, blah blah blah. But he wastes time, so he's cool.
Life without risk is like Kool-Aid without the sugar... it just ain't gunna be sweet. SO grow some balls, don't think and just do it.
