Our neighbours have 3 dc's (around 4, 9 and 12) who spend a lot of their time sitting on top of the fence that separates the two gardens (the fence is reasonably high already, but they manage to climb on top). When they're there, they stare into our living room or when we're in the garden their gaze follows us around whatever we're doing. The youngest is also very loud (screams and shouts rather than talks) - not a problem if it's in their garden as I accept that children just are noisy, but it's very annoying when she shouts over the fence in our direction for considerable lenghts of time when we're trying to spend a relaxing time in our garden. Their parents never seem to tell them off about this! But somehow I feel a bit rude to very obviously increase the hight of a section of the fence...
