Years ago, my then-girlfriend urged me to read John Gray’s Men are from Mars, Women are from Venus. So I did. It was an interesting read. But it was really nothing I and any other red-blooded American male didn’t already know about the differences between men and women, and how the two – very differently-wired human sexual creatures – might better interact with one another. But it was in a neat little one-volume package that we males could refer to whenever we screwed up, which – according to our female counterparts – was and is often.
