The pain of being obliged to practise concealment towards him, was very little inferior to the pain of having made Harriet unhappy.

– Jane Austen

Emma, Chapter 53. Reflected in this quote is Emma’s internal struggle over concealing things from Mr. Knightley and hurting her friend Harriet. Emma is engaged to Mr. Knightley, but she believes Harriet is in love with Mr. Knightley.
