Observations

Brother-in-law John watching an ad with Kenny Rogers: That’s a old man.

My wife: That’s Kenny Rogers, John.

John: He’s a old man.

My wife: It doesn’t matter how old he is, John; he’s still Kenny Rogers.

(My wife was trying to get John to associate the last name – Rogers – with John’s – Rodgers. But John saw only a gray-haired man, and words would not alter what he saw. When his attention is fixed on one subject, having him change attention is almost impossible.)
