Even punting phones aren't infallible. I'm single so don't have the problem of a nosey OH but today I called a WG that I'd previously seen. No answer to the call so I went for plan B (a very good plan B as well). Later, on the way home, my phone bleeps to indicate a text received. Text reads " sorry hun, busy all day, call again soon xxx". Moral of the story is turn off, or at least turn the volume off, on your punting phone because you could walk through the door, give your Mrs a little kiss on the cheek, and your secret punting phone suddenly rings or bleeps in your pocket - game over.
