Drinking is always easier when there is a game involved. Somehow when you’re forced to throw back your entire can of Jimmy because you lost the bet it slides down a lot easier, especially as the game progresses. Your alcohol is going down like water, you’re not getting the same effect as water though, you’re rolling around on the floor and laughing at the ceiling.
So you have this one friend who, whenever they drink, it’s either they’re sober or completely intoxicated, there is no in between for them. Every weekend is a repeat of the last, they will never learn.
