we cannot control how anyone else behaves.
sometimes, we cannot even control how we behave.

but we can attempt to control how we react to others.
so, if the other person is being a disrespectful jerk, just ignore them and continue on with your life.

as tinman posted, jerks are often their own screening service (as a potential client, colleage, or friend).

keep on trucking! (oh, and sucking & fucking)
