A: Hey, dude. What are your plans for tonight?
B: Nothing, my boss called me and asked me to do night shift. Steve's sick so he can't do it.
A: That sucks! You're missing all the action. Well, I'm gonna go clubbing anyway. I left some commando chow in your fridge waiting for tomorrow if that's okay.
B: That's cool. Well, I gotta go bust my ass off.
A: Good for you. I'm gonna go raving with these spanish chicks. Wooo!
