I am not a stupid person. I learned how to read at the age of four. I was the valedictorian of my high school class. I graduated from college Summa Cum Laude and a member of Phi Beta Kappa. I have honed my razor sharp wits by running around after three small children (or maybe that has translated into Mommy Mush Brain). All I know is that I am completely stumped today. I have totally disappointed my five-year old son. For the life of me, I cannot figure out how to transform Optimus Prime back into a truck.
