This may sound a little weird, but I'm actually thinking of doing this in SG....
http://www.freehugscampaign.org/http://www.youtube.com/watch?v=vr3x_RRJdd4It may look stupid. It may sound stupid. Personally I think it's kinda fun. How many times when u are walking down a street and felt all alone? Just look at the reactions of the people in that clip. A simple gusture brought a big smile onto their face.
I'm juz thinking, how many of u people here in these forums will actually go hug a stranger if this event is to ever take place?
