In dubliners the dead, what does gabriel talk about in his speech?

Gabriel delivers his speech, in which he praises Kate, Julia, and Mary Jane for their hospitality. Framing this quality as an Irish strength, Gabriel laments the present age in which such hospitality is undervalued. Nevertheless, he insists, people must not linger on the past and the dead, but live and rejoice in the present with the living. The table breaks into a loud applause for Gabriel’s speech, and the entire party toasts their three hostesses.
