In the past I've used Miss/Ms. My preference is Ms, I think Miss sounds very young.
I've never been married. Two teenagers. Live with them in my own house, everything paid for by me as I've always worked and never had a man to depend on, I can't imagine ever risking my financial independence.
I've noticed that post 40, I'm almost always assumed to be 'Mrs'. School teachers, tradespeople, even the bank, refer to me as 'Mrs'. I used to correct it but now I can't be bothered. Why should men not be defined by their relationship status but women are?
So aibu just to let the assumptions continue and even start ticking 'Mrs' on forms, so I don't have to correct people who obviously think most women over 40 are 'Mrs'?
I tried to correct the bank, who seemed to think I'd need to post all sorts to get 'Mrs' changed to 'Ms'. So I left it, that was several years ago, so obviously the bank thinks I'm happily married...
