My best friend is Bob. He is 15 yea

My best friend is Bob. He is 15 years old. We are both in the same class. He works very hard. He is never late for school and he does well in all his lessons. He is always ready to help others. My math is very poor, so he often helps me with my math after class. His parents are both teachers. They are very busy, so he often helps do the housework at home. He is a little shorter than me but he is very strong. He likes playing football very much at school. We often play football together and he plays it pretty well. He gets on well with us. Everyone in our class likes him.
