Sing to yourself, dad

Singing along to the radio on the way to school this morning, Ian tells me, “dad! Can you please stop singing?”

Dad: “But I like singing!”
Ian: “Well, you can sing when you’re all by yourself.”
Mal: “Ian, you’re not the boss of dad.”
Dad: “It’s ok. I don’t mind being quiet if it’s bothering Ian.” Fun part of the song comes on again so I loudlly hum it to myself.
Ian: “Dad! Are you humming?”

lol.

Dad: “Yes.”
Ian: “It’s ok, I don’t mind if you hum.”
