Driving while married.

Mark (reading the vanity license plate of the car in front of us):  "DOCENT. "

Me:  I guess he’s a docent.

Mark:  That’s one of those words that I always think sounds like it ought to have a different meaning than it really has.

(Pause.)

Like "nubile."

Me:  What do you think "nubile" sounds like it ought to mean?

Mark:  I don’t know.  It sounds like it ought to have a sexual connotation.

Me:  "Nubile" does have a sexual connotation.

Mark:  I thought it meant "of marriageable age."

Me:  That doesn’t have a sexual connotation to you? 

Mark:  No, it just means, you know, old enough to get married.

Me:  Well, if you’re old enough to get married, you’re old enough to have a sexual connotation.

Mark:  But you might not be marriageable.  You might be already married.

Me:  I think it means young, attractive, and female.

Mark:  Also a person might be nubile, as in of marriageable age, but undesirable for some other reason.

Me:  Okay, okay, whatever.  So what do you think "docent" sounds like?

Mark:  Like something that ought to have a sexual connotation.

Me:  What?!  So what do you think it ought to mean?

Mark:  I don’t know, I’m just hoping to get lucky at the Science Museum.
