Reality of Santa ClausBecause he is untruth and not real! He's real for kids only.
Rather Santa is real or not is in your perspective. While it is true that Santa is not a rolly-polly man who wears a red suit, lives at the North Pole, and delivers presents on Christmas Eve in a sleigh pulled by 8 reindeer, the spirit of Santa Claus can be very real, depending on people's outlooks.
look why say that some kid could be out there reading this and you could really be ruining there life so there for let there mum or dad tell them that not you. Some people forgot their sense of magic and imagination.
