Dad is driving. I am sitting in the back. There is a mosquito flying in the car. I want the mosquito to go, but dad always says, "Don't open the window when I'm driving!" And he is right. So I don't open the window.
Now the mosquito is on Dad's ear. I want to hit the mosquito, but Dad always says, "Don't touch me when I'm driving!" And he is right. So I don't. I don't do anything. The mosquito sits on his ear for a long time.
Later, Dad scratches his red ear, "I think something bit me," he says.
And he's right. But I don't do anything. And very, very quietly, I say, "I know."
