Just for fun, you may want to start writing your story in advance (don't be too wordy), then fine tune your story to the point, possibly with a past pic or two, that way when you're approached, you'll have the story ready. If they don't, you'll have a story to pass down to your grandchildren
Keep the story short and sweet;
humans today have short attention spans and don't like to read paragraph after paragraph.
Perhaps put your story on here~ we'll proof it for you, but remember short and to the point!
