We are a “take your shoes off” house. Yes, when you enter the front door we have a rug and bench that allows you to take your shoes off and leave them by the front door. That might make some house guests uncomfortable because they are wearing socks with holes in them, or maybe their socks do not match. I do not care about your socks and, if you are barefoot and want socks, just ask.
My house is usually clean (depending on the day of the week you arrive). Regardless, what we do not want is to bring the dirt from the world into our home. Think about all the places you were before you knocked on our door? You probably are not out mucking a horse stall (or maybe you are), you might have been in a mall, or on a hike, or in the grossest bathroom in town. I do not care, I want it to stay at my front door and not be brought through my house.
Think about it.
I remember as a counselor at summer camp, we each had buckets of water outside our cabins where we would stick our feet in before entering the cabin. The hope was if you washed all the sand off your feet before entering you would have less at the foot of your bed while sleeping. You could always tell the campers that never cleaned their feet, because when they changed their sheets half the sand from the lake was in the middle of the cabin floor.
While I do not think of all the gross bacterias and funky things that can spread, this article does shed light on why it is important to leave shoes at the door upon entering a home. So are you a shoes on home, or shoes off home?
