Rome has the Forum.London has Speaker's Corner.Now always­on­the­go New Yorkers have Liz and Bill.

Liz and Bill，two college graduates in their early 20s，have spent a whole year trying to have thousands of people talk to them in subway stations and on busy street corners. Just talk.

Using a 2­foot­tall sign that says，"Talk to Me."They attract conversationalists，who one evening included a mental patient，and men in business suits.

They don't collect money.They don't push religion (宗教)．So what's the point?

"To see what happens，" said Liz."We simply enjoy life with open communication(交流)．"

Shortly after the September 11,2001 attacks，they decided to walk from New York City to Washington，a 270­mile trip.They found they loved talking to people along the way and wanted to continue talking with strangers after their return.

"It started as a crazy idea，" Liz said."We were so curious about all the strangers walking by with their life stories.People will talk to us about anything：their jobs，their clothes，their childhood experiences，anything."
