Santa's not real?????!!!!

Yesterday we reached a new milestone with our oldest son, Anthony! Anthony is 7 years old, and has always believed everything Mommy told him! Well, at least I thought he did!!!

Yesterday I was working on the computer, when out of nowhere he says, "Mom, I wanna say somethin!". I say, "Okay, what Bud?".
Him: "I know it's not real!"
Me: "You know what's not real?!"
Him: (Pointing to his 4 year old sister! He SPELLS out) "S-A-N-T-A C-L-A-U-S!!!" (No E at the end, that is not a typo!)
Me: "What makes you think that?"
Him: "Well, I've kinda known since that time (December 2006) that we busted into the room and saw all the stuff!" (In the room was all of the Christmas presents, the door had been locked, and our then 2 year old daughter managed somehow to get it open! Go figure!)

So here I am feeling like the biggest idiot of them all, how could I have not known that he didn't believe in Santa for 2 straight Christmas', I mean come on!!! So I decide if he is old enough to ask that seriously about it, and smart enough to know not to say it, but to spell it instead in front of his sister, I am willing to let go of this phase of my boy's life....no matter how hard it is to allow him to grow up...I gotta give in sometime right?
