And though he exclaimed at the term, she found that it had been pretty much the case... Elizabeth could not help smiling at his easy manner of directing his friend...

Elizabeth longed to observe that Mr. Bingley had been a most delightful friend -- so easily guided, that his worth was invaluable; but she checked herself. She remembered that [Darcy] had yet to learn to be laught at, and it was rather too early to begin. (ch.58)
