skype to keep in touch with friends and family: use the old, but still useful, snail mail.
I love getting postcards so still send them to others, and by doing this I also help the small shop or street vendor, get a tiny wage, while making friends happy . You can do it too.
I buy a pile of postcards and the same number of stamps; then while waiting for a bus, or a meal, I sit and address them all, then as I have spare time, or a tale to tell, I write on the postcards and post them when I see a post box.
This post-box was in the north east of Cambodia.
