I live on a very quiet cul-de-sac with great neighbors, except for one house! They have people coming and going all the time, including, on occasion at 3am, when a couple of them will come over and drink in the middle of the cul-de-sac, play basketball, and get into fights. Let me tell you, if you haven't been woken up by drunks playing basketball at 3am you haven't lived!!!!
They also have multiple small children living there, and they are constantly playing in the middle of the cul-de-sac, which is ok, we just drive very slowly, except that the 'adults' in charge seem to think that it is ok for these children to lie down and sit on the pavement, it is very difficult to see a small child sitting in the middle of the road, no matter how slowly one is driving. They also allow their children to ride their bikes and scooters around wildly, including in and out of the piles of yard waste that we have collected in neat piles along our roads, as that is how they are collected by the city, so all of that waste becomes strewn over the streets.
