Encountered from Reading Lucy
“It was several minutes before I resumed reading Lucy’s letters, and when I did, it was at a slightly treacherous remove, as if I were withholding information from her-like faking surprise at an outcome you already know”
I understand this word now because the author felt like she betrayed Lucy because she already knew the outcome.
