So my nieghbor has cancer he is up in age I would guess upper 60's. So when he was going through treatments he was very ill and didnt come out of his house. So when I had time I would mow his lawn for him. I did it for like 2 months straight. So I came home 2 weeks ago and he mowed all the grass I have outside of my fence which is about 5 feet to the street. Well my prob is he cut it at about 2 1/2 inches!! its st. augistine and we are reaching upper 90's and flirting with 100's over here! so the rest of my lawn is at 4 inches except for the area outside of my fence. He was so excited he told me he had extra energy and wanted to return the favor man he was sooo happy! So I let it slide, I came home today and he cut it again! I either cant find the words to tell him thanks but no thanks or I just dont have the heart to do it. IF you guys saw his face you would feel guilty too, the guy was happy. So what to do? let my grass burn in the sun? or tell him to stop it?
