well, you'll never know. it may not save someone's life, but it feels good.
i was feeling a little down the other time and was just walking down the streets of Orchard. and just nice, some kids were there giving hugs. i just went up to them. "hey, i need a hug." and honestly, it felt good.
but this might not apply to everyone, i understand. just sharing how i feel. don't come flaming me now. heh.
