That reminds me of my mother coming out of the shopping centre while my dad was sitting in the car waiting for her only to get into a similar car 3 cars down. There was another elderly man sitting in that car too and she started on him with out looking at him to clean the car up. When she did look up at him she realized she was in the wrong car. My dad was sitting back watching all this just about wetting himself laughing. Mum was not happy with dad for letter her get into the wrong car..... but dad couldn't stop laughing.
Life is what happens when you've made other plans.
