It probably isn’t that they are so clever, but that they cannot stop bragging about it.
I am now 70, and finally married to an intelligent woman. In my younger years, I was physically attracted to two women who turned out to be not very bright. I was never repelled by a woman’s intelligence. But, I have never liked the company of anyone who couldn’t stop bragging about their degrees and how better they were than everybody else.
Yeah, Im sure its in your face all the time....
