A while back, my wife was dropping my daughters off at our church. The lot was fairly empty as they walked from the van. The son of a friend of ours had just pulled in in his little truck. He jumped out and started walking towards the building. What he didn't see was that his truck was following him towards the building! Evidently he had accidentally bumped it into neutral, and it was rolling along slowly behind him. My wife and daughter both yelled at him, waving and pointing at his truck. Not being able to hear exactly what they were saying, he turned, smiled, and waved right back! He finally did notice the truck, but not before giving an opportunity for my wife and daughter to later laugh at his expense.
Check your brake and have a great day. Stick.
