Small Talk

We were relaxing. He was tired after playing a round of educational apps on his iPad,  I was taking an off day.
I was imagining my day tomorrow,  he was flexing.  Maybe he was,  I didn't notice, but I heard him say,
"Is that a new aircon? "
I was caught off guard. " What? "
" Is it new?"
"Yes."
"Oh."
Then he went on and played some more apps.
I was still stunned. Did my boy just made a small talk with me?
