A sincere handshake/hug can do wonders!
The 'Attitude Rockers' did a practical demonstration of the same. They called the folks over for small audio-visual from youtube http://in.youtube.com/watch?v=vr3x_RRJdd4
This set the stage for an interesting exercise. All were given a piece of paper... and asked to interact with people they were not in touch with. This was to be initiated & closed with a handshake/hug.
The chaos was worth watching... pics in the slideshow on the right!
Good show, attitude rockers! We are expecting more such stuff from you...
