My best friend is Thanh An. We came to the same Archimedes School, and we have been friends for 1 year. Thanh An is not short and not tall, he has a normal height. He had a short black hair and a big black eyes. He is very kind and smart, especially in Math. He is funny too, he makes me laugh even when I feel bad. I like to be friends with him. Because he is very smart at Math, we created a Zalo group to do our homework. I will tell you my secret: I sometimes copy his Math homework too (HAHAHA). I hope that I can be friends with him forever.
