If you have a good neighbor, you are a lucky person. You have someone who cares about your needs and your property , who is helpful in the little day-to-day situations that come up, and who is supportive in difficult times. A good neighbor is someone who, for instance, understands that your children may sometimes run across his lawn , even though you tell them not to. He'll realize that children can be careless about things like that, and he won't make a big fuss about it unless it becomes a regular thing. In the same vein, he knows that you'll understand if some of the trash from his trash cans blows across into your yard. A good neighbor is also respectful of your property. For example, he asks your permission before doing anything that gets in your way. This means he wouldn't plant a huge tree between your houses without asking how you feel about it. If he wants to put up a fence, he would let you know first. He might work with you to decide where it should be placed. A good neighbor would lend you some milk if you ran out. He'd give you a ride to work if your car was broken, and let your children stay at his house in the evening if you got stuck working overtime. You would do the same for him. Both of you would help make the other's life easier. When something really awful happens to you, like a death in the family, a good neighbor will offer to help in any way he can. This could mean something small, like making some food to put in your fridge to feed visiting relatives. Or it could mean something big, like helping you get through the sadness of the funeral. I think only someone who has experienced a bad neighbor can really appreciate a good one! A good neighbor can be a good friend. He can make a total difference to your life.
