You're bringing back the memories Timbo! My first primary instructor just wasn't getting through to me. It didn't help that I had some exposure to instrument flying prior to officially beginning my primary training... I was transferred to the Chief Pilot. After seeing what I had, which wasn't much; he did something very unexpected. After he finished yelling and just after turning downwind, he said "Take off your shirt!" I hesitated and the yelling started again, "Take off your shirt!" We covered the entire instrument panel and it was then that I started to learn to fly.
