Exactly, everyone knows that. But cards are all about cya (cover your ass)
You are looking at this from the wrong perspective, the receiver. Of course no one cares about getting the cards, but cards aren’t sold to them ... cards are sold to the giver.
From the giver perspective, it’s just enough to ensure the receiver can’t ***** about you forgetting about their birthday or whatever. Even they don’t like it, they can’t say anything about it.
It’s like the trump card. You both know what it means, but they are forced to recognize that you remembered them, no matter how ****** they feel about it.
