An elderly woman was telling me about how shocked she was when she tried to give her sixteen year old grandson a goodbye hug and he froze with his arms hanging at his side. She interpreted this non receiving or giving back hug as a sign of something very odd. Not everyone likes to be hugged by everyone and before we impose our squeezes it might be better to take someone's hand between both of ours and look at the person and gently smile. That says alot too.
