what is the characteristics of the character's in three men in boat?

J., the narrator and alter ego of the author. He is single and a resident of London. In this wry tale of a holiday on the River Thames, J., of no stated occupation, is representative of the English middle classes. J., who is something of a hypochondriac, commiserates with two friends, George and Harris, about their need for a restful holiday.

George goes to sleep at a bank from ten to four each day, except Saturdays, when they wake him up and put him outside at two.

Carl Hentschel (the founder of a London printing business, called Harris in the book), with whom he often took boating trips is someone he has known since they were boys.
