I clearly remember sitting in a sidewalk cafe in Florence writing postcards to all my friends in the States. That was in 1965. I still write an occasional postcard when I think it’s a particularly beautiful picture, but the world has changed incredibly since 1965. Now it’s more likely that I will snap a picture with my iPhone add a short text message and email it on the spot to a friend in the United States or Europe. Instant communication is the norm now. That takes care of the touristy kind of correspondence that lets friends and family know that you’re still alive and well in some far off place.
