Sorry, what? The knowledge that a couple is expressing gratitude for every gift they recieve somehow cheapens the expression?

When someone does something nice for me, I say, "Thank you." That's how I was raised. I've probably said, "Thanks" a dozen times already today. Does that devalue the significance of the expression the next time someone holds a door for me, or offers me a stick of gum? I think not.

Why shouldn't we each get a non-bill in the mail now and then, in order to hear that we matter to those we may choose to gift? It's called a thank-you note, not a thank-you novel. I don't understand why writing them is considered such a burden, if unwrapping the gifts is no trouble at all!
