The Original Ape:
I laughed at the topic "rockheads" which I am assuming to be the name that you give these individuals ... !
On topic however, I know women that have been scarred so deeply that they will not even entertain the thought of a relationship, my aunt for one. But she is a very lovable, attractive and amiable person, she simply won't allow men in her life.
In a way though, it may qualify her as a "rockhead"!
(BTW: Some of these people I know are male rockheads!)
Interesting topic!
