Do you call those people of the older generation by their first names or by Mr. or Mrs.?

I grew up calling most adults Mr. or Mrs. with a few exceptions. I still call people older than me Mr. or Mrs. with a few exceptions. But there has been a shift in how I’ve observed other people addressing elders. Many people use first names no matter the age difference.

I think that the older generation deserves respect and this is one small way I can honour that. I know it’s old fashioned but it is something that I feel still holds value.

My children’s friends have always called me Mrs. but some of my oldest son’s friends have started using my first name. I’m not exactly comfortable with that but I don’t believe in demanding people use a certain name so I let it slide.

Do you use Mr. and Mrs. or are you a first name user? Why?
