I have not received replies from half of the folks my message went out to. I had to ask every single one of them for their address, so that is how often we have done this kind of thing. LoL. They are welcome to take up my offer, they are welcome to decline my offer. They wouldn't be rejecting ME, so the motivation behind their decision not to respond is none of my business. I want to send Christmas cards to bring smiles to faces, not to get validation in return.
Again, I don't mean to make this all about the Christmas cards, it's just an example. And I'd like to hear more examples.
