For me growing up Christmas time was always the most fantastic exciting time of year and you'd stay up until three in the morning. You'd hear the parents wrapping in the other room but you knew that also maybe they were in collusion with Santa Claus.
No matter how close to personal experience a story might be inevitably you are going to get to a part that isn't yours and actually whether it happened or not becomes irrelevant. It is all about choosing the right words.
