Calendargirl
I was quite proud to take my husband’s surname when we married. It helps that his is a more ‘common’ name than my maiden name was, I was always having to spell it out.
I preferred being ‘Mrs Calendargirl’ than ‘Miss Calendargirl’ also.
Back then you had more status when married, or so it seemed.
Which is probably one of the reasons women don't like being referred to as Miss in middle age. An unmarried friend says it makes her feel like a prim governess or the tragic friend left on the shelf in a Jane Austen novel. Neither of which describe her in the least.
Also, as so many women now work, own their own businesses, look after their own financial affairs etc it is appropriate to have one formal title for addressing women in all official or professional correspondence. Or should clients, bank managers, business acquaintances etc have to run around trying to find out women's marital status before sending them a letter or email?
