We live in small cul de sac of about 20 houses. There is a small communal green area which is very rarely used. We are the only people with kids so I use it sometimes to play with the kids (our garden is tiny), just messing about or having a small picnic. Othere people in the estate are quite a bit older than us so no small kids.
Anyway one family (parents and grown up son) have a dog which they let out to run around in the evenings. I have no problem with this. He is a lovely dog, and just runs around a bit and chases a ball. He is never out for that long.
However I have started to notice that this family never clean up after him, and the little green area is now covered in dog poo. I can't really let the kids play there now. I don't know the family very well, except for saying hello. I am not sure how they will react if I point this out to them, after all they can hardly be unaware that he is doing it, they are out with him all the time. Its a such a small estate I don't want to have a falling out with neighbours especially ones who know a lot of the others well. Maybe just easier if I clean it myself?
