What age did you first tell your parents that you knew there was no Santa?
I remember when quite young, I told a bloke dressed up in red and white with an unbelievably long beard (Osama Bin Laden?) that he couldn't possibly be Santa and that he was a fake (I was asked to leave...) My nephew on the other hand believed in Santa right up til about 10- my sister said "it's sweet..." to which I replied "No, his friends will laugh at him. And his uncle."
Kids, there is no Santa. Sorry
