Dear Mr. & Mrs. Ozzy,
This is really sad. I agree with those who say you should pretend you didn't get their card and go anyway. Maybe they're just trying to cover their backs.
Peace & Love be with you.
If the truth hurts most of us so badly that we don't want it told, it hurts even more grievously those who dare to tell it. (Judge Ben Lindsey, 1869-1943)
