.
The first woman, who has a brother who is an alcoholic, promised God that she would never drink alcohol again, either wine or beer or spirits, if God gave a special grace to her brother to give up excessive drinking.
The brother has just given up drinking.
The second woman prayed and felt that God was asking for a penance for her to do for her brother who is an alcoholic. She gave up beer for the rest of her life. An month after her promise, her alcoholic brother gave up drinking, cold turkey.
God honors prayer and suffering.
