here is the part of an email you have received from sam, an English- speaking friend. though my sister's quite a bit younger than me, we are good friends most of the time. So teel me about a relative of yours who you see a lot and why you enjoy being with him or her. hope to hear from you soon.

Dear Sam, I am glad to hear that you also have such a relationship with your sister. I am writing this letter so as to tell you about my brother who is younger than me about 2 years. I have a younger brother and my sister's much younger so we do not often do the same things. however, I have a cousin brother who is the son of my uncle. He does not live far from my house due to I could tell him to go out easily. Although we are different gender, we have the same hobbies namely playing guitar, reading books, and traveling. I often teach him about Maths problems because I am quite good at maths and he teaches me how to play guitar without seeing guidelines on the Internet. At the weekend, my family and he go to picnic together. furthermore, he always helps me when I am in need. In conclusion, he is such a friendly person that I enjoy being with him. I hope that you could tell me more about your sister later. Best wish, Gigi.
