Mediation
This is normally the first thing we consider when dealing with low-level antisocial behaviour.
Mediation helps the person behind the antisocial behaviour to understand your feelings. A independent mediator will arrange for you to meet and help to guide your discussion towards finding a way forward that does not cause you distress.
Mediation is often the best way to deal with antisocial behaviour where problems between you and a neighbour have been caused by a "clash of lifestyles".
