To say the truth, I am never sure about Johnny's reactions. Every other day I discover something new about him and his habits. And I am suspecting this is the same, the other way around. He taps the side of his nose with his finger to show to me, he masters the subject he is talking about ,and I think he is suffering from nose's allergy. I heightened my eyebrows to indicate "No" and he thinks that I am surprised with his question!
