Who would you hug? How much would you have to care about them to hug them? Is hugging a sign of love and affection?
Happily - my wife, my brother, my Mum & Dad
Slightly grudgingly - close friends (because I know if I don't they'd be a bit offended)
Only if I really can't not do it - anyone else
Yes, it's a sign of deep friendship/affection
