I personally am strongly against the e-x,y,z of everything from mail to cards.
When I was a teenager, we used to have a tradition within my family, which was sending paper cards to all relatives for the new year. Cards would be bought, written with the best hand writing, with the very positive wishes and posted to all relatives one by one.
What is best is to find those cards in your library years later, read them again. Wishes for new year would be like: "........wish you respect based days of love....."
It is one of those things I hope will not be lost to this dizzying speed of electronic life in everything. Same with newspapers and magazines. Nothing gives the same pleasure as reading from the physical newspaper and magazine itself.
