I have two words for you: CORDLESS PHONE
We are a business line at home, so I take the cordless with me to every room, including that one. Can't afford to miss a business call.
Loo is French and has come to mean the toilet..........can't recall the original word. We were informed by a guide in England what it was. I think it was something referring to what they yelled out, in the really old times, when they dumped the chamber pots out the windows.
