RE: One Letter too Late

The purple truck reminds one of the chocolate brand 'Milka' ;) Furthermore, choosing purple deliberately suggests a willingness to transform and grow. The letter pushes the inquisitive mind over the edge, opening up new possibilities. Whether there's a deeper connection between the purple truck, the letter, and the other puzzle pieces is left for the reader to dissect -- in accordance with your last paragraph: "funny how quickly strange things become part of your life when you let them."
