I have recently started reading your book and was hoping DH would but he doesnt really read so I will just have to extract info and force feed it to him.
I laughed when I read this as I've heard this so many times about our book.

It's the way guys absorb material like this. I know personally of about 25 guys who can quote the Men are from Mars book but didn't read a page of it themselves. They learned about it from their partner reading it and saying, 'Listen to this, this is exactly what you do'.

I myself learned about the whole 'men go into a cave' theory by having my wife read it at me at night while I was trying to read a Robert Ludlum thriller.
