It's definitely the season of Goodwill! My wife and I were in London last week. As we parked the car we realised we didn't have the correct change for the parking meter. I asked the first passer by if we could exchange coins. He gave me the coins and refused to take mine! We thanked him and put the coins in the meter and realised we still needed more (it was an expensive meter!). So we asked the next person if she would exchange coins. She gave me the coins I needed and refused to take mine. I was Boom Boom-ed twice within 5 minutes and it felt wonderful!
