Veteran's Day

My six year old comes home from school on Wed and tells me that he needs to thank his grandpa's that fought in the wars.
I sadly had to inform him that all his great grandpa's that fought in the wars have died. He got this look on his face like WTH?
He goes on to say, " What? Guess I will have to wait until I die to tell them." Nothing is less then dramatic with my little kindergartner. I told him that he has to be an old man when that happens.
