For starters, your bff doesn’t care if you have stinky farts, so long as you take it ok when he nicknames you “Stinky McHot T*ts.” Also, he tells the jokes that make you laugh the hardest, so hard you fart, and he laughs at that.
Marrying your best friend is pretty easy. You just have a guy (or girl) who is your best friend, and you legally bind yourself to him through an outdated business contract and your dad gives his dad 25 goats. I’m not sure really what’s in the fine print, but it is fun to laugh at him when he tries to tell me I’m supposed to obey him now. Actually, according to my husband, it sounds like the marriage contract is some kind of lifetime warranty on me, and if I do things wrong, like forgetting to fetch his ps3 controller, he tells me he’s sending me somewhere to be re-educated on being a wife. I tell him I watched literally ALL the Married… With Children episodes possible, and offered to watch them again, but apparently there’s more to it than that.
So that’s it! Good luck!
