How is Elias Like an Elephant?

He never forgets...anything. Or so it seems. He remembers how most of his books go (unless he can read too). He somehow knew that one of the 5 purple beads was missing. There are 5 other colors of beads, so how did he know one of the purple ones was gone? Can he count now? He knows that we see a clock when we go in the tunnel, which we do once every few months. He points to a postcard on the fridge and says, "Wendy." Sure, her picture is on it, but we haven't seen Wendy for months (she lives in Durango, and has been to visit maybe 3 times). Not that Wendy isn't so much fun that no one would forget her, but still...I can't seem to remember what I did yesterday. Little kids' minds are amazing. Too bad we all have to grow up.
