yeah right once again
bt this is revenge....isnt it?
couldn't you tell the answer
u cn tell him about the harmful effects of loud music from which he can suffer bcz although a person does not care for others but he surely cares for himself , and u can also advice him if he is interested in listening music he can use headphones.
with this you can solve ur problem without any fight
