What if I'm thinking of not mowing my lawn to my neighbours dismay?
Why do you want to not mow the lawn?
I want to piss them off
People are expected to mow their lawn and keep they house nice looking on the outside. You could get a fine if the grass is too long and then the city will bill you for it.
I don't see what the big deal is
It's important to mow your lawn and keep your yard looking nice. If you don't do this, you risk your neighbors reporting you to the city. It's best to avoid the drama and maintain your lawn.
