Can I ask just one Miley Cyrus question? Why does my iPad have a ringtone option, and like why can't I turn it off? And like why did my iPad just start making a ton of weird sounds all of a sudden? And like, why is there a "tweet" sound option where the default is a "tweet" sound that barely sounds like a bird? And why would anyone want that to happen?
