Not really sure. I said I believed in Santa longer than I did because I wanted Santa's gifts.

I remember once when I was a teenager at home with my family when somebody knocked on our door and when my dad opened the door in walked somebody in a Santa suit with gifts for my young sisters who were still young enough to believe in Santa. Not my mom or dad or me knew who was playing Santa and it was totally unexpected. My sisters were delighted to see Santa in the flesh and my mom, dad and I all sat there looking at each other thinking who the heck is this?
