Where is the phone?

This morning my grandmother phoned. Nothing strange in that, but it got me thinking because I couldn't find the telephone. You know that new-age problem that has arrived with mobile technologies. So my cordless phone was somewhere downstairs and I was upstairs. When I got to the source of the sound, I could hear it, but strangely the sounds was muffled, it was underneath some cushions on the armchair, and had fallen down the back. Whilst digging it out I did wonder how many people in the world, at that precise moment in time, were doing the same as me.... looking for their telephone ;-)
