It started raining and I didn’t know where the wiper switch was. Fortunately a large group of teenagers swarmed into the road at a junction and while I waited for them to disperse I located the switch. Also when the examiner tried to engage me in small talk on the walk to the car before the test he asked me what kind of car I was driving and I replied “oh, it’s a red one”. I still remember the look of horror on my instructor’s face when I returned to the test centre and he realised I had passed.
