Finally, I picked him up and unceremoniously tossed him (lightly) into the car seat.
He was angry.
"Leave me ALONE!!!" he shouted.
"We do not talk to our Abba [father] that way," I replied.
He looked at me with his still angry face and said:
"PLEASE leave me alone."
I started cracking up. Couldn't help it. He got the joke as well.
