Having great neighbors can be a wonderful gift, particularly if they have children who are pleasant and not spoiled. When parents have little control over their children or really don't care what they do, then you may have major problems. Children of all ages want and need limits and do respond to voices of authority. If you allow any child to be in control, trouble may loom. I was always glad to have kids play at my house when I was home because if there was a problem, I could take care of it right away. A good friend and I were talking the other night and she told me of the neighbors' son who she had next door. For the last few months he had started bouncing a ball at all times of the day and even late at night. He was probably trying to score baskets and the patio was right behind her bedroom. She said she had been sleeping in another bedroom away from the neighbors' back yard, so she could not hear the bouncing. Then finally one night when she was tired, she went outside at 10:30 and said " You need to stop bouncing your ball now."Immediately, the youth said "O.K." and the bouncing stopped. She realized she should have done something like that several months before, but did not know the neighbors and hated to cause problems. I(t will be interesting to see what happens now, but I suspect the youth just needed an adult to say "Stop." Apparently his parents, were afraid to set limits or were just never home.
I remember a man telling me his mother used to lock him out of the house after he had had breakfast and he had to entertain himself the rest of the day and forage for food from kind neighbors. Not all parents love their kids and many wish they had never had them. Lining next to neighbors like that can be a nightmare and even making a call to child protective services can cause terrible problems and may not result in helping a child. There are some great social workers in child protective services and there are some who just want their monthly check and don't care about the children they are supposed to protect.
So if you have problems with a neighbor's child, I would try to talk directly to the child or teenager and see if you can make them understand that certain behavior is just not acceptable.
