When my son was about 2 years old he said "Mom, you wan' hear my poem?" "Of course", I told him so he said: "I walk, I talk". A few weeks later... "Mom, you wan' hear my new poem?" "Sure, Simon"! He then said: "I walk, I boing". Like, a bouncing ball.

I never thought about that during the 12 years he spent doing Irish step dancing. hmmm...
