[WhoIsDaffy]

I dont really feel any overt need to respond to anything else in your post.

we have a dif. of opinion.
you have the view that one must observe and cow-toe to society,
I dont.

as for your example:
it depends.

have i just met someone and have been invited into thier home.
I would not put my feet up on thier furniture, wherever i was in the world

Is this person my friend, ive known them from a while, and i feel the need to put my feet up.
im gonna say
"hey, my feet are killing me, mind if i take off my boots and put them up for a while?"

or if this person was a very good and close friend:
I would take off my boots, put my feet up, point out the fact that i know this to be offensive in his/her culture and then enquire as to where my cold drink was.
