Thank-you cards — heartfelt （真心的）expressions of gratitude for gifts, services and general kindness — seem to be rare in an age when the Internet continues to reduce human touch.

    Although our society has changed greatly over the past centuries, the etiquette of thank-you notes has not. While most people would agree that thank-you notes under these conditions are necessary, there are still those who forever delay or are forgetful for unknown reasons. And at no time of the year are thank-you notes more visible than June, the month of graduations, and the beginning of summer parties. “It’s a must-do thing. A real ‘thank you’ does not come by e-mail. It comes in the mail in an envelope. And what comes out of an envelope is a beautiful thing to touch and to handle and to pass around for everyone to read,” said etiquette expert Letitia Baldrige.
     Don’t think for a second that Baldrige is old-fashioned. Handwritten thank-you notes — any handwritten letters, for that matter — have taken on an air of extra importance in this e-hyper  (电子狂躁症的) world. Baldrige remains hopeful that the art may be enjoying a renaissance (复兴).
