I only have two hands MOM

As I was making supper yesterday, David was in the kitchen with me, wanting to help set the table.
He had two plastic cups in his hands and was going to bring them to the table.
I ask him to also take some forks and spoons.
He stood there with a cup in each hand, holding them out to me.
"I only have two hands MOM" he said as if I had just asked him the silliest thing in the world.
