If rock music is to be believed, dozens of girls in every school are named Sally. If Bad Manners are to be believed, Charlie Brown’s baby sister grew up, moved to the rough end of London and became a skinhead. I’ve never met anyone named Sally, or even known of one. As for little Sally Brown, you can imagine what you like. This particular Sally sounds like a real cool girl, though she probably has a switchblade in her boot and doesn’t mind using it.
