Describing my friend

About my friend, Phill. He's 20 and he is a college sophomore studying computer science.
He is a funny person. He can make anyone around him laugh, and whenever I have a bad day, he knows how to make a joke to make me feel better. He is very believable, I can tell him my secrets or problems without worrying. He is also sociable, he and has a lot of friends.
He loves music and sports, especially football, we often play football on the weekends. He's good at cooking, he has many recipes on lots of different dishes; you should try his soup.
He also has some negative things you can say about him, for example, he is very talkative, he is always on the phone, chatting with his friends. And sometimes he may make noise with his music, if so let he know about it.

not sure what you meant with your last sentence... should we alert him that his music is too loud? if so then I would write: if so then let him know about it.
