A 65 year old lady suddenly started learning to swim instead of her usual routine of going to bingo. Everyone was curious and asked her: "why the change in your interest?" The lady, with a look of helplessness replied: "Whenever my son and daughter-in-law quarrel with each other my Daughter-in-law always asks my son : - "If your mom and I fall into water, which one would you save first?" So, because I do not want to put my son in a difficult position, I am learning to swim!" A few days later, her son and his wife were quarreling again, and the daughter-in-law unreasonably asked: " now tell me! If your mom and I fall into the water, whom will you save first?" The husband replied: "I don't have to get into the water. My mom knows how to swim, she will save you." The wife refused to relent: "No, you have to jump into the water, and have to save one of us. Which one will it BE?" Her husband replied: "Then I'm sorry to say you'll die anyway because I don't know to swim, and my mom will definitely save me first!"
