Get a tablet. You can take that to the toilet too!
Personal rules of etiquette:
1) Bathroom reading must be of the paper variety. Newspapers, magazines and books are ok.
1a) Newspapers taken to the bathroom must remain there until disposed of. Do not return newspapers to other areas of the home. Each bathroom should contain at least one Reader's Digest, age is irrelevant.
2) No electronics in the toilet area. In a public restroom the electronic item must be stored in a personal bag or a pocket. It should not be out. At home, tablets, cellphones, laptops, etc. should remain in the living or bedroom areas and never enter the toilet sanctum.
2a) Never, ever, ever text or snapperface or instapost or bookerchat from the restroom.
2b) Never, ever, ever answer the phone while on the throne. Ever.
2c) Never, ever, ever, ever, ever take photos of your excrement. I have a former friend who found this hilarious and would occasionally send me images of the latest rectal construction. I cared not.
2d) If you are so important that you MUST answer phone calls while launching the brown canoe, invest in a bluetooth accessory for that portion of the house. That's still horrible, but not quite as bad as sitting there with your phone in your hand.
