High School Shenanigans

You’re gonna decide who to hook up with, whether or not having a hot mom and a hot sister is gonna be a problem or an asset, how to get your motorcycle done before the summer, so you’ll be able to go on that road-trip you’ve been planning for a couple years, and generally just trying to work out what you want to do with your life.​
