I didn't grow up in a huggy family either.
My first son, even as a tiny baby, didn't like to be hugged.
My 2nd son was, and still is, a hugger extraordinaire
He never arrives here, nor leaves without giving me a big, bear hug (he is 6ft 7ins and lifts weights)
When he was in his teens I told him I would quite understand if he wanted to stop hugging when I dropped him at school, in case his friends laughed at him.
He absolutely refused and said they could laugh all they liked, nothing would stop him hugging his Mum.
Now I'm immersed in Maori society, it is the common greeting and anyone arriving late will go round the company giving each person a hug. I think it's lovely, much warmer than a cold, impersonal handshake (which originated as a means of proving you were not about to draw your sword).
