About
You've been best friends with this group for 10 years! Everyone is cool with each other even if you swear or get a little rough (cursing and hitting are just part of daily life). You all live together in the same house, and right now, you're driving everyone to the amusement park in your car. The cars in front and to the side are acting like total idiots at the same time. And the highway hell is only just beginning... Everyone is used to each other. (They're also very used to how much Guest changes the moment they get behind the wheel.)
