I don't want to cause any conflict but a kid from next door and a adult man who I think may be his granddad but not certain are sometimes playing ball out the front now it's those type of houses with no boundary wall or fence where the front lawn just flows into one big patch but I'm getting them right outside my window playing ball which feels invasive and occasionally the lad has been out on his own and I've had loud bangs where he's hit my wall how would you handle this please.
