A Scotsman is the exception that disproves the Pseudo Concept.
Another precious misconception of my youth, was that men were men because they had short hair and women were women because they had long hair. In the early l940's that was pretty much the rule so that to children then, it appeared to be the distinguishing bond for the sexes.
That, and the fact that only men wore pants and women skirts. (It was World War II that changed all that when the women took men's places in the factories and got their hair and skirts caught up in the machinery.)
At that time I was really loath to put on a skirt because I though it might actually change me (we didn't have Mr. Rogers in those day). Now, as an adult, of course, I do it with impunity.
And then, when I saw a rough looking bearded Scotsman in kilts and with long hair, it was a traumatic experience to think that there, for the grace of god, might be my or anybody's mother.
