I am, Sir, a brother of the Angle.

Walton’s line is a courteous self-identification: he presents himself as a “brother” of the fishing “angle,” i.e., a fellow angler, invoking a sense of fraternity among practitioners of the sport. In Walton’s angling literature, fishing is not merely a means of taking food but a contemplative pastime associated with patience, civility, and harmony with nature. The phrasing also carries a lightly humorous, old-fashioned formality (“Sir”), suggesting a polite exchange in which shared membership in the angling community becomes an instant bond and a warrant for conversation. The quote thus encapsulates Walton’s broader ideal of angling as a social and moral fellowship.
