You idiot, ever since I first heard of Santa when I was 4 years old I NEVER believed he was real. Any kid who is SMART AND LOGICAL would never believe it either. My parents never gave me stupid delusions of it either. I used to go around my 2nd-grade class and say Santa wasn't real and the teacher told me to stop but I didn't. You are preventing children from developing their logical thinking skills if you tell them it's possible to travel to every household in Christendom in a single night. Considering in TV and movies Santa spends at least a few minutes inside a house delivering presents and eating cookies. The time doesn't add up. Those were my exact thoughts at 4 years old and that's how I deduced he couldn't be real. If your kid doesn't think like that he's retarded and you're not helping him by saying that's possible.
