Just out of curiosity, how many of you ask that people remove their shoes when entering your home? I grew up always taking my shoes off when we entered our home, or someone else's. I get so grossed out at the thought of everything that could be embedded in carpet. When people come over to our house and walk inside with their shoes on, I get so distracted by the fact that they are wearing their shoes that it's sometimes difficult for me to enjoy their company. I may be a bit OCD, but that's how much it bothers me! But, seriously, I live in Wisconsin, and it's winter...Who would wear their snowy/salty shoes and boots into someone's living room?
