My Dad was very affectionate towards us. Up to the day he died he used to hold my hand crossing the road...got told off, in front of my mates, for swearing....In the pub he'd ask me what I wanted to drink and always, always, ask if I wanted a packet of crisps.
Yes we hug....We have cuddle Wednesday. I'm not included in that because I'm a girl....and girls get cuddles whenever they want.
Obviously they can hug at any time...but on a Wednesday they make the effort to. It's quite amusing to watch.
