The rule prohibits you and your family from any relationship with your neighbors beyond “hello” and “goodbye.”
Timothy broke the neighbor rule by agreeing to have a beer with his next door neighbor. Timothy then found himself becoming close friends with the neighbor. Timothy then had a falling out with his neighbor and he stopped feeling comfortable around his home. Timothy, you dumbfuck, you broke the neighbor rule. Now you want to sell your house and move far away from your drunk asshole neighbor.
