Who is Morris Lipkin from Bread Givers and what is their importance?

Morris Lipkin is a young man who boards with Zalmon the fish-peddler. He writes poetry for Fania and attends school. Soon, Fania is also attending night classes. Morris dedicates his collection of verses, "Poems of Poverty," to Fania. He promises to talk to Reb in an effort to gain approval to marry Fania but Reb freezes him out so completely that Morris leaves without speaking.
