I've been helping Santa with his mail for many years. My children and their friends would see my desk covered with NP stamps, calligraphy pens, ink and watercolors...and of course they'd want to know what was going on. They not only unequivocally accepted the fact that I worked for Santa, they brought me special requests and lots of questions.
Their questions, as well as questions children asked when they saw me at shows, helped to inspire this letter.
Flying reindeer and getting down a chimney are a couple items Santa addresses.
