We‘re a shoes off house and my parents and my husbands parents had the same rule at home although adult visitors were usually not asked to take their shoes off when we grew up but they also didn‘t go upstairs.
Despite taking shoes off in her own home i have to ask my MIL to take her shoes off EVERY SINGLE TIME. I have explained that i have a crawling baby who’ll touch everything and put her fingers into her mouth and i‘m trying to teach my toddler not to run in with his shoes on..
MIL usually just sweeps in and i stop her in the living room or kitchen and ask her to take them off to which she replies „but they‘re clean“ (i haven‘t witnessed her ability to fly yet) and „I’ll get cold feet“ (we have floor heating and i then offer her warm socks).
My floors are also not disgusting in case anyone is wondering because i‘d understand wanting to keep shoes on if that were the reason.
Is it rude to ask other adults who do it in their own home to take their shoes off? AIBU? Any tipps?
