person A: i live next to a football field and every football season i hate living here
person B: Oh yeah_comma_ why is that?
person A: Because they park in my driveway!
person B: I would have them towed!
person A: i have signs up this year_comma_ so i can do that legally!
person B: Oh so you have to have a sign up to legally tow them?
person A: Yes. Which i think is wrong.  If they are on my property i should have the right without the sign.
person B: Or you could just park behind them so that they would have to knock on your door before you let them out.
