I don't remember a specific age the transition happened, or if I ever actually believed it, but I remember my family getting a PS3 one year for Christmas "from Santa". Sometime in the Summer, I was in the car while my mom was on the phone talking about the PS3 she got for us needing a repair or something. Again it wasn't that I believed in Santa at that point, it just became a core memory of "Oh you lied about that"
