"Hey, we need milk. Could you get some on your way home?"
"Sure. Do you have a preference?"
"2%, but I'm supposed to be cutting on fat. Get skim."
"You left your room a mess. Again."
"You're not Mom, bro. Chill out."
"I may not be Mom, but for the time being you're living in my house. If you don't like it, find your own place."
"Are you seriously kicking me out?"
"I'm not kicking you out, I'm just asking you to be more considerate."
"Would you mind picking up some milk on your way home?"
"I guess. You got a preference?"
"Skim. My doctor says I need to cut back on fats."
