But You're a Parent

Conversation on the way to school this morning:
Emma (6): Mommy, why do celebrate Memorial Day
Me: um...well...let me think...I'm not 100% sure (I know..sad)..I think it has to do with soldiers but I don't really know
Emma: But you're a parent..you're supposed to know everything
Lily (4): No Emma..Daddy knows everything, not Mommy

Thanks Lily...thanks a lot...
