Hand Shadows

Ivan and I were lying down on the bed, in the dark some time ago. Then, I started playing hand shadow illusions with him, making him guess out each of my hand shadows. So, I did aeroplane, bird, dog, rabbit and little worm. And I did those for several rounds, and by then, he could already identify all of my hand shadows. With him feeling proud ....... and me lost with ideas, I bended my arm and moved my elbow towards him.

[me] : What's this Ivan? *I don't even know what is that in the first place.*

[Ivan] : ........................................................
He was obviously thinking hard ... what can that be? hmmmm ...

[me] : Can't guess?

[Ivan] : ..............................
Still thinking hard

[me] : Elbow !!!!!!!

[Ivan] : HHhahahahahhahhahahaha
He laughed out real loud. Which is great ! That's a sign of my son understanding a joke and join in for a hearty laughter. :)
