Family Get Together

I had fun this evening playing with my littlest niece. We played a new game. In this game, I hold her and ask her "What's wrong with you?" very insistently and very fast, all the while tickling her. I stop when she tells me that nothing is wrong with her. Then I let her go, and she immediately returns and tells me something is wrong with her.

Repeat indefinitely until one of us is exhausted.

I find it hard to refuse them,
Because it's so fun to amuse them.
