Everyone needs some down time though - I think there's nothing wrong with a game boy for the waiting room!
Feel very inadequate here..I gaze out of the window, fiddle with my phone, look at my watch, tell my children to be quiet, sigh, tut, maybe chat to them to check the symptoms which brought us there in the first place have not disappeared...I do not engage them in word games, timestables or other useful things, though I did once read 'The Giraffe and the Pelly and Me' all the way through, out loud, with funny voices for all the characters, and the whole waiting room was listening in the end. My daughter made me promise never to embarrass her in such a way again. Mind you, she was 15 at the time.*
