That made me smile as I remembered visiting my retired (now long dead) grandfather about 30 years ago on a 2000 mile + trip down South from my new job in the Northern Territory. He was a tough old farmer and horseman of great repute who had run cattle up in the Victorian highlands and un-fenced wild snow country during summers and once in the late 1950's had led a Government expedition of 40 or so on horseback for a week or two through the wild country to survey a potential new road route through the mountains. I hadn't seen him for about 7 years and when he opened the door I said "G'day Pa" and for the first time in my life hugged him and kissed his cheek (something I have never done to another male, relative or otherwise before or since). The look of shock on his face I will never forget and it was probably the only time in his life it ever happened to him either. I still don't know why I did it then or now.
Funny how different cultures can be. *Maybe I should have used your graduated approach
