Waiting time

As I waited outside for Mrs Rex to emerge from her outpatient's appointment there seemed to be a lot of people in wheelchairs smoking as they were either wheeled around or parked outside for a fag break. It was too cold to hang around for a detailed study of the subject matter so I went back to the car for a heat and waited on a phone call to pick her up.  An hour and a half later I got the call. The next study needs to be on how to find a parking space within walking distance from the hospital
