Thanks Roland. I am always learning something new though. Just when you think you have them figured out, they will surprise you with something new. So, I just go with the flow.
My brother does have them figured out though. He was a pharmaceutical rep and when they evaluate drugs, it is always a matter of whether a drugs' benefits outweigh their side effects. Women, it turns out, are the same way. As long as their benefits outweigh the side effects, you are ahead of the game.
In other words, some are more trouble than they are worth. Good words of wisdom I think.
