I wanted this encounter with the man I'd come to think of as a second father to be all emotion, embraces, tears. But I realized Otto would probably just shake my hand formally and we would have very civilized time and that would be that. I was prepared.
Could you tell me, what he was prepared?
He/she was emotionally prepared for Otto to be very formal and polite, not warm and friendly. The person had decided in advance they would not show disappointment if Otto didn't greet them with warmth.
