Something I believed in as a child

Something i believed in as a child was in Santa Claus, I believed in it so much that i actually thought i saw him once. I remember an older friend of mine told me that he wasn't real and i still didn't believe him. I can't recall the day i found out he wasn't real but i remember i was so shocked and i was mad at my parents for lying to me, but it was still fun to believe in it in my childhood, me and my cousing would always fight to see who sees Santa Claus first.
