Should I be worried?

Some people may think it rather SILLY but mainly at the request of our granddaughters the “little” rooms in our house have a small stock of books and magazines. 
Today I noticed a new one which was a bit odd as they are away on holiday! You will see from today’s blip it has a strange title “DON’TS FOR HUSBANDS”. 
Am I being SILLY and should I be worried – is wife trying to tell me something? or is it there to amuse?
