whatever you are into is cool. given the choice, I'd rather an instructor say "I don't know" instead of a bedtime story....but thats just me.
(I was the type of kid that, on my 8th christmas, refused to open my presents until my parents told me the truth if santa was real or not. lol sadly, a true story. they leveled with me though...and you know what? knowing the truth didn't make me feel better about christmas, but I enjoyed the presents all the same. I won't spoil it for you, and let you find out for yourself where the presents come from.
