The Bishop was in the habit of selling everything he could lay his hands on to help other people. He sold off his estate and spent his savings in bits and pieces to help the poor. Recently, he sold the silver salt-cellars too. Persome was, thus, fed up with her brother’s generosity and called him incorrigible.
