I've learned a long time ago you have to do what is good for you. I am the kind of person that once I know you, look out, I will hug the stuffing out of you. Until I do it is a handshake, unless I know you like or need a hug.
My mother was a hugger, my father isn't.
I just see it as a sense of security.
As for the rest happening in here, well that is the reason I believe the thread was started. It is for everyone to share, the good, the bad, and know that they aren't alone.
