when i have the chance, i'll open the door for anyone, young, old, man, woman, whatever - it's just a nice gesture and gives me a chance to interact, even if it's in a small way, with people - and when they do it for me, i'll always give them a smile and a thank you - not sure why the fuss about a simple gesture...
when i lived in SF, i'd make it a habit of saying hello to pretty much everyone when i was out walking about - just a 'hi' and a smile, nothing more - i like to think it got passed on - sometimes i'd get a surprised look, but often, i'd get a smile back. kind of made my day a little brighter. it's the little things that we forget sometimes, that have the most impact.
