Where’s the dirt?

Some people make a big thing of leaving their footwear outside the house. I almost always take off my shoes too, in my own house as well as that of others. Because footwear carries dirt inside. Period.

So it amazes me that people pass judgement, and virtuously carry prejudices, hatred, meanness, taunts, insults inside after reverently removing shoes outside. That’s the only thing that carries dirt into the home? Seriously???
