Envelopes and Postage Stamps went with childhood for me...as a young immigrant in Canada, my Grandparents would write me in Dutch, and to keep me interested, my grandfather would collect as many stamps and send them on. Holding some real paper in my hand with the pictures and history of my homeland, and the countries we had immigrated to and from made it real for me. I became interested in Geography, and History seeing the colonies and the heads of various European Kings and Dictators as they controlled Africa and The Middle East. Recently I read that the post office system will probably be gone in 10 years, with UPS and Fed Ex taking over. The era of affordable mail brought about by the Universal Postal Union which allowed people worldwide to send paper, handwriting and pictures that could be held, read, savored, and stashed for the children, will probably cease, as Facebook Accounts and e-mail substitute for real paper, a pen, a stamp and a legacy.
I remember my folks complaining that since the phone came into the world back in the 40's, people no longer came to visit as often, and since TV, people didn't eat meals together as often, and on and on. I'm sure one day an envelope with a well crafted stamp will be as rare as the antique washboards and the horse and carriage...but I shall miss them...miss counting the Christmas cards, where the number meant how much you meant to others, miss soaking stamps and looking in the catalog for its companions, seeing drawings of history before Wikipedia could answer all your questions. I know, at 66 I'm history, too.
