In multiple instances of US media, I've seen characters wear shoes inside a private home.It always struck me as odd; Why would one wear it? For comfort? Isn't it more comfortable without the shoes..Or with slippers?
And hey, don't you realize that it is DIRTY? What especially baffles me is that Sheldon and the others in Big Bang Theory wear shoes inside the apartment, even with Sheldon's extreme germ phobia. Isn't this exactly the sort of thing he would crack down on?
So, my question is; Is this really common-place in the US, and why? How do you feel about it?
