I want them ... Bashny.Net

Behind the wall is very loud children laugh and something very rumbles
Judging by the sounds, the neighborhood kids fun throwing each other cabinets, periodically jumping down from the mezzanine between throws.
I have no idea what to do to make noise so. Personally, I have never in my childhood are not so loud raged. Zadolbali they are, and it's from morning till night.
But worst of all, I want them ...
Tell me, is this normal or an urgent need to treat? Or maybe it's too late? ..
