Nurse Carmen springs immediately to mind. IIRC, he’s neither a nurse nor a Carmen. The name comes from a TV show popular around here in the '80s or so, I think.
I think mine is gender-neutral, but it’s often misread as ‘rhubarbarian’ (barbarians are masculine, right?). And everyone seems to assume I’m a man at first.
I’ve been told that my usename has a masculine ending to it. I don’t know enough about Latin to say “cat” in it, so I’ll take their word for it. In any case, I’m pretty sure the bones in the middle ear are neither male nor female.
I have always assumed you were male, partly because I would pronounce your handle roughly the way I would say “a lesson.” However, in light of your post, I speculate some might conjure a resemblance of “Alison” in their mind’s ear.
