From today's NY Times (link):

Jayson Littman is not especially lonely, or religious, or in need of cash - things that strangers might assume upon meeting him.

He is a financial analyst who happens to think that New Yorkers could use a hug. So it was, a month ago, that Mr. Littman began distributing hugs - free - from 1 to 4 p.m. on Sundays in Washington Square Park in Greenwich Village.

"At first I thought no one would respond," said Mr. Littman, 26, who lives in Manhattan. But on his first Sunday, standing before a giant hand-lettered sign that reads "Free Hugs," Mr. Littman and a friend embraced 200 people in two and a half hours.
