Newly initiated brother

While visiting a newly initiated brother at home one day, the new brother's wife took me to one side and said her husband had started behaving very strange since joining.
I asked in what way?
She said that he locks himself in the toilet for hours on end mumbling to himself with his little blue book.
Later that evening I turned the talk to lodge, and asked him how he was getting on.
Oh fine was his reply.
I asked him about his behavior and if there was anything wrong.
No, was his reply.
So why read the book there?
Well he said "Its the only TYLED room in the house"....
