Move Over Einstein or maybe Van Gogh?

My kindergartener has always had quite a photographic memory. He was about 16 months old when I first remembered the time he knew where I had placed things that done weeks before. There was also a time when we didn't think he was listening while my husband and I were looking for a certain something and he got up and pulled it out for us. Ever since then, we would ask him if he's seen the remote on this table or the keys on that dresser, and almost every single time he'll remember where he saw it last.

In school, they are starting to write in Chinese characters. Memorization plays a role on which brush/pen stroke means what. One wrong placement of a stroke can mean a whole different word. Quite obviously, he has excelled in this as well. Well, today I found him drawing Arthur (one of his favorite cartoon character) without copying from any materials. All purely from his photographic memory. I am still in awe of what his little brain can do.

But can someone tell me, why the heck can't he remember to eat his school lunch? I ask him every day "Did you eat your lunch"? He'll say "No". Not because he doesn't like the broccoli or the meatballs. Nope. He simply says "I forgot!"
