In a society where people are afraid to physically touch each other and withdraw more and more into their own private worlds, the need for hugs is going up, but the demand isn't being met because people are just too afraid to show their emotions openly.

To second abducted's writeup, go out there and hug the people you love, the people you tolerate, and the people you can barely stand. Or just go out there and hug someone you don't know that well. If the opportunity strikes, seize the chance. There are a lot of shy people out there who like being hugged. Go out there and allow them a higher comfort level so they can pass on the hug. Go ahead. Make their day.
