Free hugs

Hey - I saw people offering free hugs in Pitt St mall today! I thought they were just a figment of Dr D's... a hook created to hang a one liner off.. . But there really were about 3 people holding carboard signs that said free hugs.

Of course, I took a wide berth around them, being concerned that a complete stranger would lunge in for an un-invited full body contact if I got too close. So I sadly remain ignorant of their point. World peace, I would image. I suppose there are worse things. Tell me more if you know what this is about.
