We are a shoes off house. I've grown up that way, I've lived in countries where that is the norm and with small children
And crawling babies I hate the thought of dog mess being trapsed into my house of which there is plenty around.
I am not a clean freak, my house is not full of precious rugs or floors. We just don't like shoes in our house.
Recently a couple of friends have been noticeably offended that we've asked them to take their shoes off (so politely) before they come in.
Why are people like this?
