When I married 40 years ago, each partner keeping their own surname was more common. That was “our” way of keeping things distinct. We didn’t do this, but I admit to feeling a little squeamish about setting the tradition aside. Today, not so much. I like traditions, the simple, non-evaluative, non-invasive, non do-what-I-say kind and hope we maintain some of them. But disconnecting from old habits and fixed ideas, masquerading as traditions, is fine by me.
