It worked great for me when a Mexican family moved in across the street with like 4 kids that made all sorts of fucking noise. I became friendly with the parents and they just about gave me permission to beat their kids myself if they got out of hand or just give them a call. Latter they moved which really sucked as around each Christmas they would hook me up with these killer tamales.
