I think I am old fashioned sometimes too...
However, I have never prescribed to teh Mr Mrs thing... Especially teachers - my kids teachers are all called by their first name. I actually don't know one of their surnames!... ... I grew up thinking I had lots of Aunties and Uncles - really it was my mothers way of skirting around the first name issue. Aunty jan was really Jan Smith! No aunty at all!

I am 42 so I learned the same - 2 spaces after a full stop, signature, addy etc...
It's all changing and evolving.

I am in the medical profession & when I began we had a Matron - she was Matron to everyone... Then there were the surgeons who were Mr... Then the Doctors who obviously were doctor, Sister, Nurse etc. Noone every referred to anyone by their first name. EVER!

I now wouldnt dream of calling the doctors I know by Dr... They are their names to me... But like Leesa I have always gotten away with stuff others may not! I would never call now answer the phone Sister... However, I would state my name & if needed my role. I am very casual with names - not with my work but with the frills. I am not one who cowtails & I think the "toity ness" of some titles gets me annoyed... HOWEVER - there is a place... My little girl has crawled onto my lap so I wil BBL
