She has returned home and found the drawing by Humphry of
Mr. Byng, another other small drawing. She recalls the capital picture he presented of her son, and having offended him at the time by saying she could not afford to commission any pictures from him. She therefore assumes his sending charges to the house as some sort of joke. Mr. Byng sat for Humphry at his express request and did so thinking him a fellow liberal gentleman. Mr. Byng is hurt and so she writes in his stead.
