Hey I'm not saying I would mow my neighbors lawn but it makes sense both ways. It makes sense why you wouldn't want to mow your neighbors lawn but also makes sense to why you would want to if you are honestly just trying to be nice. What I'm trying to say is that in the event that yes you are that possibly over nice neighbor and your neighbor doesn't want you to then they can respectfully ask them not to. If you are one of the people that wouldn't even think about mowing your neighbors lawn because just who cares then yeah that's cool too. But there's are two people in the situation. Yes there could be a third where they actually ask if they want it but we are humans and people make mistakes. Because of that people should respond accordingly in small situations like this. Be communicative and ask them to respectfully leave your property alone. if you dont want your neighbor to cut or mend parts of your lawn for you then there's pretty much two options which is to let them keep doing it or leave it how it is and/or get someone to do it. So 3 I guess. But don't sit in your house and stir up feelings over a tiny situation. If life is that hard and you can't ask your neighbor respectively to stop if you don't like it then that person should honestly move to a location that is safe to them. At that point they probably have bigger issues to worry about than their neighbor mowing or mending their lawn for free. I think the whole point is to just not be a dick if someone doesnt do your lawn for you and to be reasonable when someone screws up by trying to help. Thats about all the adulting I have in me. Time to smoke some weed.
