I have a best friend, and his name is Minh. Minh has been my classmate since we were in elementary school, and it means that we have been friends for more than ten years. Minh lives near my house, so it can be said that he is also my neighbor. He is a chubby boy with curly black hair. He wears a pair of very thick classes since he is short eye sighted. He has been wearing them since he was a little boy, and it is hard to recognize him without his classes even for me. Minh is a good student at our school, but in return he is pretty bad at outdoor activities and sports. He spends most of his time to study, and his free time is used for playing video games or eating. I am his best friend, but my appearance is total opposite from him. I am a tall and slim girl, and I love to play sports like basketball and badminton. I try my best to take him outside, but I usually fail to do so. Instead, I will sit down and play games with him, and after that we will go outside to get something to eat. He helps me a lot with the school work, and we usually study together. We do our own homework, but after that we will exchange our notebooks to check other’s result. Every morning he stops by my house and waits for me to go to school together. We ride our own bike, but recently his mother has an idea for him to work out that he has to take me to school on his bike as his morning exercise. Although he is not a prominent boy, most of the classmates still like him because of his kind and gentle personality. I am proud to have a friend like him, and I think that we are totally suitable for each other.
