Say goodbye to Twinkies

I own my yard
I pay my neighbors kid to cut the grass every week for 25 dollars
He says the other kids get 30 dollars a week.
I say well its 25 dollars a week , I am sorry I can’t pay you anymore than that man.
He says well I want 30 or I won’t cut it
I say okay you are no longer cutting my grass.

How can I do this ?? Because it’s my yard, my lawn mower, my gas, my weed eater. I planted the grass when it was just seeds, watered it, made it grow into a flourishing yard. Now my grass may not be green as it once was, as a matter of fact there’s a lot of brown dead grass, but it’s still worth cutting. So son do you want the 25 a week to cut this grass knowing that I pay you every week on time rain or shine. Or do you want to take your chances trying to get your friends yard for 30 dollars.
