We are as green as we possibly can, but we do send cards for various occasions and that's one thing I don't think we would stop. I just think it can mean so much both to give and receive a card.
I don't think it's particularly 'un-green' either. We make most of our own cards - we've got huge boxes of craft materials, some bought and some recycled or scavenged. My own 3 kids put such a lot of effort into making their cards, one does a lot of cross-stitch, another is into more scrapbooking techniques.
Any cards we do get are re-used. Some for the traditional gift-tags, others we keep and use to make more cards or calendars or similar.
It just sounds a bit sad to me, the thought of never sending cards. I know you can ring etc, but it's just not the same. A lot of my relatives live hundreds of miles away, some of them on their own, and I know that they love to display their cards and have a tangible reminder of someone's birthday wishes. A phone-call is in addition to that, not instead of.
An email just isn't the same to me I'm afraid. Although I must admit, I don't like cards where someone has just quickly scrawled the quickest message possible. I make sure when I write mine they get a bit more 'message' or preferably a separate letter in there.
That's another thing isn't it? Do you all just send emails and never letters? I do use email, it is a quick and easy way of keeping in touch, but again it's still not the same as writing or getting a 'real' letter.
I don't think being ethical or green is always that black and white, I suppose that's where we're all trying to find our own ways of doing things and balancing different issues.
