If you believe in Santa then that means you're younger. Don't read the separated sentences below if you believe in him. I personally don't believe in him because I'm a teen and I know who really gives them out. If you do believe in him then you know you get presents only if you're good.
Santa isn't real. If you believe in him then really all you got correct is that you get presents. Now, not everyone gets presents but you know. You just didn't know who gives them it to you. Some parents like to tell their kids that it isn't Santa already because they don't like lying to their children but other parents just like saying that to make the children more excited and to be good in order to get presents and it's what they're used to.
