4 Year Old SAT Words

So Jacob was putting a puzzle together the other day. It was one of those puzzles that has three pieces - a beginning, a middle, and an end - egg, tadpole, frog. He was searching for the end jack-in-the-box when he yells out, "I am so EXASPERATED!" Seriously. My son. My 4 year old son just blurted out an SAT word that I didn't know when I should have. So I call grandma...have to share. She asks him what it means...to which he replys the exact context that he originally said it. Nice. I have a brain on my hands. Nice.
