The magic whistle was a sassy drag queen who fell in love with her singing coach, and absolutely hates the reader solely because he/she is not the singing coach. However, the magic whistle eventually bonds with the reader, no matter her thick shell.
Or maybe some angry British dude who vows revenge on humanity, even though his attacks are lame.
Or maybe a Wal-Mart cashier who hates life in general and does no good for the reader.
Or maybe— you know, I think I haven't slept properly in awhile.
