I read an article in Real Simple last month about 5 old-timey rituals that should make a comeback. And of course #3 was writing a real letter.
"The handwritten letter is an endangered species. It was driven out by telephone calls, which are themselves being driven out by texting. Now, people tell me, when someone dies, they get a text from their friends that says, "Oh, sorry." Texting makes sense if you want to ask someone to get a cup of coffee. More serious occasions, like a death in the family or a wedding, call for a handwritten letter. It's not hard: Take a blank piece of paper and write." -Judith Martin
I could not have stated it better myself!
