Responding politely when someone asks to visit your home when you never invited them can be done with tact and consideration. Here's an example response:
"Thank you for thinking of visiting my home! While I appreciate your interest, I currently have some personal commitments and prefer to keep my schedule a bit more private at the moment. I hope you understand that it's not a reflection on our friendship, but rather my need for some quiet time. Perhaps we can plan to meet up outside the home for coffee or lunch sometime soon instead?"
This response acknowledges the request positively, sets boundaries respectfully, and suggests an alternative way to spend time together in a different setting. Remember, it's essential to assert your boundaries while maintaining kindness and understanding.
