Maybe the complaining neighbours should be invited to the tea and chat. Maybe the Broomleigh Housing Association should install more benches and set that time of day for the entire housing residents to have social time. Even to go so far as to install a gazebo or pavilion for those rainy days. It would be astatically pleasing to the neighbourhood and facilitate good neighbours. Some pensioners may even enjoy gardening.
There are other ways around disputes that does not entail harm to ones freedom to enjoy the small pleasures in life.
