Christmas Cards annoy me. You have the blank ones that allow people to write their own message in them, but in actuality someone either just writes Happy Holidays, Merry Christmas, or one of the many other various forms of those two phrases, or they use the blank card as an excuse to write a whole well thought out letter. The problem with the latter is that many people put Christmas cards on display which people tend to open if they see them on display, which means that in turn your personal letter is on display.
There are also the kinds of cards which the Happy Holidays or Merry Christmas greeting is already in there and then the person writes little else since everything is summed up in those few words. Personally I hate either one, mainly because even if you still write a letter, a card with a predefined image on it seems impersonal. I would want to send out cards that either I designed, I hand made, or had something to do with me and my loved ones, something like a picture as the card, or maybe one I photoshopped, either way I’d want it to be personal. I’d also customize the Merry Christmas with their names and maybe a short message, that even if it was generic and mass produced, it could still be seen as somewhat personal.
