This conversation gets repeated throughout the day:
Guy: “Hey, what’s going on?”
Guy: “You going to come by the party later?”
Girl: “There’s a party?”
Guy: “Oh yeah.”
Guy: “Should get going about eight.”
Girl: “Okay, cool.”
Here’s what actually happens: if sufficient people show up by magic, it’s a rocking party, and people are sent out to purchase additional beer. If not enough people show up, it peters out and everyone leaves. But every day they’re fishing, which means that if you’re a girl, the claim that there’s a party actually carries almost no value at all, and since the frat boys are drinking every night, there’s no cost to claiming that there’s a party later.
