Hugs. On Valeintine's Day.

Are you a hugger? I've always been, and recently was reminded that not everyone is when I greeted a long-ago friend with a hug and he seemed taken aback. Remember Leo Buscaglia? "Dr. Love" was his nickname in the 80's when he had a series of shows on PBS. He was a huge advocate of hugs. [He died in 1998.] Anyway, according to this story, hugs may be about to be mainstream again.
