Dear... (your friend's name),
It's great for me to be your pen friend. Because of that, I would like to tell you about myself and my family so we will get to know more about each other. I'm a student at .... (your school's name) and my favourite subjects are English and Biology. One of my hobbies is listening to music. My favourite DJ is Alan Walker and I like the song "Play" best. Second thing I want to tell you is somethings about my family. I live with my parents and my little brother who I call Panda. Next year I will have a baby sister, I will name her Ice bear.
Can't wait to know more about you.
Cheers,
...(your name)
Chúc bạn học tốt!!!
