"Hey Zach, how many days till Christmas?"

Zach's family has just moved into their new home before the holiday season begins. As they settle in, they are introduced to their new next-door neighbor Dave. Zach observes some curious behaviors that lead him to wonder, "Do I live next to Santa Claus?" Neighbor Dave wears shorts no matter what temperature it is-he really likes it cold! And he disappears at odd times. Plus he always seems to know exactly how many days before Christmas!

Keep track of Zach's jolly neighbor and see what you think. Is Neighbor Dave really Santa Claus?
