Is an unmarried woman over 30 (never been married) referred to as Ms. or Miss?
Is either offensive?
I have two older (as in older than me, not as in old) cousins that have never been married. They are pretty sensitive to this fact. They get mad whenever anyone else gets engaged or married. In fact when I got engaged and they found out (in person) they didn't even smile or congratulate me, which is fine. No skin off my nose, but just wanted to illustrate that they have made it clear (vocally to the family and non-vocally) how upset they are that they haven't been married. They are 35 and 40. I am unsure on how to address their envelopes. I don't want to slight them at all and I know they are pretty sensitive. Which would be less likely to offend them?
ETA: Just to add, I'm not judging them for not being married. Marriage isn't everything, but they have made it clear (they have told us) that they think everyone is judging them. So I'm trying to be least offensive. I know it is a little touchy that I am 23 and getting married.
