You see, Mao took after his dad in that way. He was a singing cat.
When he was feeling very chatty, I would simply lean out of my computer chair and sing "All you need is Mao!" and (my hand to God) he would say "Mao." and I would go "Mao Mao Mao-Mao-Mao. All you need is Mao......" "Mao" "Mao Mao Mao-Mao-Mao-Mao-Mao." We could do this for hours.
I miss those duets.
