What is the main conflict in The Dead by James Joyce?

The plot of "The Dead" presents the thoughts and actions of one man, Gabriel Conroy, on a night he and his wife attend a party given by his two aunts. With its meticulous detail, the story is realistic in style, focusing less on great events than on subtle symbolism. Conroy is presented as a rather awkward, condescending, and self-absorbed man, but he later has a moment of self-realization when his wife tells him about a relationship she had as a young girl with a youth who loved her passionately.
