Someone who has influenced me is friends of basketball. They are is my best friend. A year ago. We do everything together. We Sports practice together. We eat lunch together at university. We talk about everything. They are important to me because they are to help tutor me on exam makes me through it. They are will behave always like to help others. They are so good to me, if I have any problem they are will give comfort and the encouragement to ease my sadness. I think that if I do not have them I would not be happy living on campus.
