Man and Boy

No woman understands how a man thinks. Seriously. The Cheating Husband told me many times - he loves me very much but that I will never understand why he did it. He never meant to do it, it didn't mean a thing. Yup, I can never understand!
I'm now reading Man and Boy by Tony Parsons. In a way, the book is another version of Men are From Mars, Women are From Venus - which I have yet to finish reading (I don't know, it's so academic and boring). Anyway, Harry, the character in Man and Boy, had a one-night stand and ended up being left by his wife. The book talks about Harry's point of view and though it does shed a bit of light about how men think and do the stupid things that they do, the real answer is never there. There is never the real reason for doing things.
Maybe there never is? I'm still reading the book. Let's see if there is an answer.
