Heard an interesting situation where a married couple with the same initial received a letter with no title - just addressed to "J. Smith". It was an amusing anecdote about the chap being called for a mammogram.
Set me wondering as to the implications of erasing sex and gender in such cases, especially if (for example) a mother and daughter share initials.
It probably wasn't the time or place to begin a discussion on women taking mens names on marriage. However in a nod to the Roosevelts, when Eleanor married Franklin, did she keep her maiden name or take his ?
