The kind of neighbor you have can make or break your living environment. If the folks next door are rude or unhelpful, it can make things much tougher for you. It becomes even worse if they refuse to cooperate or go out of their way to make things difficult.
This is the situation a person found themselves in after their neighbors went through their mailbox without asking. Even though it’s a federal crime to do something like that, the people next door threatened to keep doing it to get their way.
