withholding

"For that matter, what can a first impression tell us about anyone? Why, no more than a chord can tell us about Beethoven, or a brushstroke about Botticelli. By their very nature, human beings are so capricious, so complex, so delightfully contradictory, that they deserve not only our consideration, but our reconsideration—and our unwavering determination to withhold our opinion until we have engaged with them in every possible setting at every possible hour."

- Amor Towles, in his novel A Gentleman in Moscow
