person A: I ate a whole gallon of ice cream by myself in one sitting and now I'm not feeling too happy.
person B: Oh_comma_ I could do that if I didn't have bad teeth and can't handle the cold. I would regret it if I did though because I really need to lose some weight.
person A: Yeah_comma_ I'm telling myself that its okay since it was just a one time thing. I'll walk it off tomorrow! 
person B: Lol_comma_ burn those calories. Hope you have a high metabolism.
