I love to give and receive Christmas cards. For me it is a way to keep in touch with people who are important to me, even though I may not see them very often. I always try to write a personal message on all the cards I send to people that I seldom see, which means that at least once a year I do think about about the people I write. But the past few years, and this year in particular, postal rates mean a lot of second thoughts about who to send cards.
I chose badly for sending outside the UK. 1.20 pounds for any card over 10 grams. That's $1.92 at today's exchange rate!) Fortunately I do have enough cards that fit the bill for the lower rate of 87 p or $1.39 -- otherwise it would pay me to buy another box of smaller cards. As rates climb higher and higher, one can imagine that in the not too distant future there will be no such thing as the postal service. In the past year I suspect that I've only mailed birthday/anniversary cards and packages. Amazon means that I can order goods from the American website and so avoid expensive international charges. A long time ago, in a Universe far away during the olden days, I remember when it cost 3 cents to mail a letter!
Of course the weight (and size) of a card isn't the only consideration when choosing a card! Some people are not Christian or have no religion -- careful then to find a card that says something inoffensive such as 'Season's Greetings' or 'Peace'. Others are religious and prefer not to get winter scenes, or robins or cardinals and want a Madonna, or a manger scene or the three wise men.
A former vicar of our church once gave a sermon in which he held up a card with a picture of something inoffensive and non-religious on it (a robin, I seem to remember) saying to the congregation that this card did not convey what Christmas was all about and complaining about cards that did not properly convey the meaning of Christmas.
It so happened that the card turned out to be from the Bishop. And the Bishop just happened to be in the Congregation that day! Talk about "getting your vicars in a twist"! :-)
