I hate shoes and socks. And yes, it is quite common in much of the US to wear shoes inside the house. People thought I was nuts for wanting to take my shoes off at the door and leave them there. They even thought I was more nuts to want them to take off their shoes too.
It was a relief to move out here to the PNW and not to have to ask people to take off their shoes. They see them lined up by the door and just automatically remove them. One repair guy put on some disposable booties since he couldn't take off his work boots. I was about to kiss him for that but I stopped myself just in time.
