I'm not a Ms. I'm a Miss. I'm not married, and I'm not angry at men. About that, I mean.
When I get married, I'll change my name and turn into a Mrs. This makes things astronomically easier for the children, who will neither have to make sure people know their mother should be introduced as "Ms. Petherbridge" when their last name is Collingwood, nor go around being "Andrew Collingwood-Petherbridge," which would probably end in death aged five.
There are women who like being a Ms. That's fine. I don't mind. I'm not one of them. Some of them probably have professional reputations built under their maiden names which make it advisable to stick to it. That makes sense. Again, I don't mind.
The patriarchy has perhaps done many bad things, but the Miss-to-Mrs. one is not something that really gets my goat. I find it an aid to understanding family dynamics. I would rather not have that aid destroyed by hippies just because they like destroying things.
