mary plays her music in headphones. bob plays his music on a speaker. mary tells bob, "please use headphones. i use them so i don't disturb you, so please use them so you don't disturb me." then bob says, "i would not be disturbed if you played your music on a speaker. i am allowing you to use a speaker, so i should be allowed to use a speaker also." what should mary do?
