My latest business venture is the sale of "You're Welcome" cards - perfect items for those times when you just can't let the matter drop. Think about it: So often you receive an invitation card you didn't ask for/didn't want to some silly event you couldn't possibly be persuaded to attend. What do you do? Largely out of an irrational sense of guilt, you send a gift and a card with your negative RSVP. Of course, then the inviters respond to your card and gift by sending you another card that says, "Thank you." That's where the scenario generally ends. But why should THEY always get the last word? After all, THEY'RE the ones that started the whole thing in the first place! A "You're Welcome" card allows you to put an end to the interaction on your own terms.
