Open. Close. Repeat.

Mum and I were driving around today and she witnessed me trying out a new trick.

I held out my palm and then placed the thumb of my other hand on the palm, and closed my fist. I did it over and over again.

Then I replaced the thumb with my index finger. Open. Close. Open. Close.

Mum says it was fascinating to watch.

I don't know what it means. Probably that I'm a genius!
