Miss/Mrs Firstname or Lastname?
I'm assuming(since it's that way with us too) that it's Miss Jane or Mrs. Doe. My children's friends usually just call me by my first name but there are a small handful that use Miss in front of my first name. I prefer not being called Mrs. Lastname so I'll correct that. However, I expect my children to use Miss or Mr. or Mrs. as appropriate. I introduce people to my children as "This is Miss Jane and Mr. John. Even though my FIL has told me that I don't need to, I still knock before I enter their house because I see it as a sign of respect. It's not my home. I'll continue to knock every time and he think it's pretty amusing since he's told me several times just to walk in. Other people do it. But I won't. I expect people to knock before they enter my home as well.
