dude2: “dude, it’s 2:30 in the morning.”
dude1: “yeah, i just got home from the bar. you, uh, you want to come over and play some modern warfare 2?”
dude2: “dude, i can’t be your duty call tonight, i have work in the morning.”
dude1: “c’mon, i need you… to help clear out the favela on veteran in spec ops mode.”
dude2: “i’m there, my job sucks anyway.”
