"He who takes offense when no offense is intended is a fool, and he who takes offense when offense is intended is a greater fool." Brigham Young
Never take offense. If they meant to offend you, you are only giving them satisfaction. If they didn't mean to offend you, you are wasting a lot of friendship time.
Have a cheerful indifference to the negativity.
Go merrily on your way doing the Lords work.
