This article sums up a pet peeve of mine - people who don't write thank you notes! While it may be old fashioned, I always notice when a friend or relative sends a thank you note. Of course, many things don't merit a thank you note, but the gesture is always appreciated in my book. Perhaps I feel so strongly about this because mom instilled this habit early on. Even before we could write, she'd ask us "sign" a thank you card with a fantastic scribble.
Anyway, THANK YOU Huffington Post for a last ditch effort to revive this lost art of etiquette.
