Hide And Seek

How to play Hide and Seek according to my son:

Him: "Mommy, let's play Hide and Seek."
Me: "Ok."
Him: "I am going to count to ten and then I am going to hide."
Me: "Ok."
Him: (Eyes covered): "1, 2, 3, 4, 5, 6, 7, 8, 9, 10! I am going to go hide under my train table! Come find me!"
Me: "Ok."
Him: "Mommy! I am under my train table! You cannot find me! Where am I? I am under here!"

(My role in this game is crucial.)
