The thank-you letter to my brother-in-law is urgent, and it uses two hundred words at once.

Brother-in-law, how have you been recently? How time flies! I have grown into a teenager. I vaguely remember your words. I fought with others that day and injured others. When I was a child, I was at a loss. Fortunately, I have you! You helped me in my most difficult time, thank you! You have helped me a lot in the past two years, and I have gradually understood a lot. Is this because I have grown up? I often bully you, but you are still very kind to me, brother-in-law I feel so guilty! However, when I am older, let me test my wings, let me work hard, and then proudly tell you: I succeeded, OK? I will pay off the money I owed you last time as soon as possible, otherwise, I will feel guilty. Brother-in-law, you should take good care of your sister. If I am not around, please coax her when she is unhappy. Finally, brother-in-law, I want to say: thank you, it's good to have you!
