I do not wear shoes in the house. I’m pretty sure none of my kids do either. I don’t think my parents did….maybe Dad wore house slippers. It was no big thing, it’s just there was / is no earthly reason to wear shoes in the house. In the summer I didn’t wear shoes outside either, until school started. Rick, on the other hand, has tennis shoes on always except when he’s sleeping. I don’t understand it. I have a personal opinion that it probably isn’t healthy.
