The real power here isn't sentimentality—it's a corrective to our exhausting habit of rehearsing our own performances, worrying endlessly about being misunderstood or misremembered. Angelou is suggesting that all that anxious precision we bring to our words and actions is almost beside the point; what actually lingers in another person's body and memory is the emotional temperature we created in a room. A teacher who delivers a technically perfect lesson but makes a student feel small will be forgotten; one who stumbles through an explanation but radiates patience becomes someone the student carries forward. The paradox is that this should make us *less* neurotic about perfection, not more.
