There is no honor in taking abuse from people that mean you harm.

There is nothing shameful about erring on the side of your self interest if you are unsure about a person's intent when they engage.

People that have genuine good interests and make positive contributions consistently to the community around them will prove that out over time.

As in life, not everybody is here to be your friend.

It's ok to let people prove that they are good people. Good people don't mind doing that.
