Not sure? approach with arms wide apart; if they want to be hugged, that is a clear signal. If they don't, they will either not respond, or they will offer a handshake. I used to think that if a woman gave me a nose to knees full frontal hug, it meant more was possible. I now know it can also mean that she trusts me totally to not cross the line. You'd be suprised how far a simple question goes; "Would you like a hug"? or "I need a hug." However, if a Englishman says "I need to be COODLED, that is a horse of a different color." We have a very complex language, why don't we use it?
