Do you wear shoes in the house? Why or why not?

I’m interested to hear what the Fluther population has to say about this, seeing as how most of us are American. We do have a few Canucks, Brits and others here as well, and that intrigues me too.

I would say that most, if not all, Canadians take off their shoes in the house most of the time, regardless of the weather. Am I right in assuming that Americans usually leave their shoes on?

Why would you not remove your shoes? Why would you put shoes on if you’re not planning to leave the house anytime soon?

I’m just baffled at this whole shoe-wearing thing, and would love to hear your insight.
