My definition of a pesty neighbor is one who sends their kid(s) over all the time and calls you very often. I do not have a problem with my kids playing with other children in the neighborhood, but there has to be some limits and rules. It is not always easy dealing with them, especially if you live right next door and see them often. You want to try and be as friendly and polite as possible.
We have a neighbor who sends her kid over to our house as early as 7:30 in the morning. This is especially frustrating on a weekend when people like to sleep a little later. The child is five years old so he probably cannot tell time, but you would think that the parents would keep an eye out for things like this. The problem is that they are still sleeping and many times do not even realize that their son has left the house. At least that is the story that we are getting from the parents.
If this child comes over to the house and it is not a good time to play, we just send him home. About 20 minutes to a half an hour later or so, we get a call from the mother wondering why her son was sent back home. All we hear on her end is that he is very bored. The mother does work from home and this child does not have any siblings, so I can understand that. On the other hand, I am not an automatic babysitter. If it were up to her, this child would spend hours at our house from morning until evening. Thank God, that school will be starting next week. It has really been a hectic summer going back and forth with this mother on the phone and her child ringing the doorbell at any hour.
Even though school will be starting next week and he will not be home until after 5pm, we still have to set up some rules. First of all, he will be allowed to come over for only an hour on school days. If he rings the bell at any other time that is not convenient, he will just be sent home until his parents get the message that it is not a good time. He will not be allowed over at all before school. There were times this summer when he did come over for about 20 minutes before leaving for camp. On weekends, he must not come over before 10AM.
Some people will just never get the message, so you have to control things on your end. The best way to deal with this problem is to just keep on sending him home when he comes at the wrong time. For some reason, no matter how many times I tell his mother things, she totally ignores it and just sends him over whenever it is convenient for her and her son. Another solution would be to just not answer the door. Not answering the door and sending him home should eventually work, but it may take some time.
