I rent a terraced house, my next door neighbours own their home and we share a garden (they have half and I have half, there's a path down the middle but no fence) I had no issue sharing a garden with them - except they let their dog shit all over my grass. I've lived here since November and they only started picking it up when I began flinging it back on their side of the garden. Disgusting Tbh as I have two small children.
They still sometimes forget. They also have a huge dog that leaps up is very licky. They never walk it either so he is really wild in the garden whenever they're home (very friendly but I'm terrified of dogs and it's not great with two little kids)
But anyway back to the actual point- we never use their side of the garden. Yet they regularly use our side to play football, they let the dog run all over our side of the grass and like I said shits all over it. Since they use it probably more than me AIBU to expect them to at least cut my side of the grass as well? They'll cut their own- and then take the lawnmower around the front to cut their front garden but leave my side of the garden grass? I just think it's a bit of a piss take?
When I first moved in they would cut it but now they've stopped.. but still continue using my side of the garden 😕
