...No, hugs do NOT cure the world's ills, they are just a way of shamming friendship and goodwill so that you can get away with blue murder.
I don't disagree with you at all.
Like I said, you can do a million nice things for people, even hugs, but that doesn't mean that if you are hugged you will automatically feel the love. Love comes from within. It is a feeling.
And yes, pantodragon, you bring up another good point. Not only are there people that don't feel love if you hug them, but there are those who GIVE hugs in order to give a false love when their true intentions is to take, take, take.
