question for parents

k

hi dear parents. I live In usa, we live in a 2 bedroom apartment. I don't know why people are coming inside the house with their dirty shoes. when I'm asking them to take off thier shoes, they r getting upset. I have 2 kids and my kids are always on the floor. how about u, do u come inside of your house with the shoes? and do u let ur guests to visit ur house with their shoes?
