More merciful than I would be if I got to pick the punishment.

Aight, someone explain their point of view please. What level of volume severity have you commenters experienced? Someone listening to something has never bothered me, but it also has never been loud enough I can't have a conversation with someone. Most restaurants play music louder than I hear from a stranger's speakers. I don't get what is rude about it. Even the Everett True comic below, several of you are that on edge about a person whistling or humming to themself?
