Change my Hometown

There are many neighbors near my house. Some neighbors disturb the other neighbors.
So, other neighbors ask the neighbors "Please don't disturb my life" But I don't think This way is good. So, I will write about good ways
First If neighbors disturb to my family I will talk to the manager of the apartment. If I say to a neighbor myself. The neighbors will become angry and shy. But, If I say something to the manager of the apartment, the manager will talk to the neighbor. since the neighbor will not know who complained the manager, so people will not fight.
Second, give a small gift to my neighbors and ask "please be careful" Then the neighbors will apologize to me. I f I say something without gift the neighbor will got angry and I will fight with the neighbor .
In summary To change the neighbor I have t ask the manager to say something to the neighbor with a gift and The neighbor will change
