The policeman

Today, when I was jogging in the morning, I met a policeman. He was very bored and he needed A TASK. So when he saw me approaching one of the house gates he asked me to stop and wait for a car which was almost ready to leave the parking space. I had plenty of time to pass the gate without waiting for the car but the policeman said to me "lets wait a moment" so we waited. When the car was at the gate, the policeman stepped in front and asked the driver about stopping so I could passed by. The mission has been accomplished ;)
