Kiddies, keep a diary in which you relate all your stories as if they really happened. That way, you can review these stories to refresh your memory when needed. And, should it become necessary, you can produce the diary as evidence that you did what you claim. So be sure to surround those stories with normal routine stuff that you actually did, to make the book more credible. Include events like auto repairs and trips to the dentist, items that can be verified by impartial parties.
