This topic reminds me of an interesting thing happened last week. My daughter brought her pets two adorable parrots, outside on the balcony for a scientific observation. Unfortunately, one of the female parrot foot got hurt. Her foot was sprained by twining into the curtain. She couldn't stand or walk. My daughter was worried about it. We saw the male parrot used his beak to kiss the female one and tried his best to heal her up. At that moment, I understood what the real purpose of bring them home was. They are not just pets, they are part of my family. They told us that because we bulit a family with our spouse. When one of us is in danger, we should take care of our other half without even thinking about it. It’s natural. Famliy has a great place in comforting and putting us at ease whenever we feel tried. The next few days, the hurt parrot slowly recovered with her husband's help. We are happy, too!
