There is a group of people who are with you all the time, eat together every day, and walk on the road together. Sharing their little secrets with each other. We can laugh wildly together, and we can also cry together. Without too many words, just a look or a gesture, you will understand everything about each other. They are called sisters.
There is such a group of people who will not often appear by your side, but will share their happiness with you, let you go to their basketball games, and will always stay with you when you are most helpless and sad, even if they don't say anything, they will just watch you cry and let you know that you still have them. They are called brothers.
I am very happy, I have such a sister; I am very happy, I have such a brother
