Wince- to shrink back involuntarily (as from pain)
Colson Whiteheads seems to like using a broad range of vocabulary to convey his point throughout the passage. When I came across this particular vocabulary word it had me a standstill in my reading for a moment. It states ” It saw you wince when the single frigid drop fell from the air-conditioner twelve stories up and zapped you”. Using the context clues from the sentence surrounding the word, I was able to get some idea of what this word meant. I simply imagined a drop of ice cold waters splashing right in my face. My reaction would be much like what Whitehead describes. I still searched the word just to be sure of its meaning.
