In my country.... ummm no.

In my house. If you want to enter, ..yes. :)

I'm with Azalea: though in the US it's not exactly customary to remove one's shoes in the house, if you want to come in <em>my</em> house you're gonna take off your shoes, or you're gonna wash the floor <em>for</em> me.  I am not cleaning up anyone else's dirt!

Yes and we don't wear shoes inside the house.

yes.

DIDI, it may depend on how clean ones shoes are. Just imagine a queen traveling from one palace to another:)

In Russia streets is so dirty, and also the weather is cold except of summer, so of course we are taking off our shoes when we are coming into a flat))) First of all because it is not comfortable to stay in a warm place for a long time in shoes. *our shoes is warm enough, so your feet will become sweat soon))) And secondly, because it will make floor dirty, so it is not proper.
