How did you find out that Santa Claus doesn't exist?

It is just very bad parenting to lie to a child and tell them that a fictional character is real. santa, god, allah, tooth fairy, easter bunny, zeus, jesus christ. These are all fictional characters that we have been told were real. This is how you raise your children to become mentally ill adults. I always knew there was no santa and no god. This definitely helped me set my life straight at an early age. It is never god or santa it is always the real people who are there for you. More often than not, it is really our parents doing all that stuff for you. It is extremely wasteful to give any love and appreciation to something that does not exist. That is why it is extremely important to drop all these imaginary friends (god, santa, tooth fairy, jesus christ, etc) and start appreciating and loving the real people who are there for us every day :). So, THANK YOU MOM! I love you ^^
