“Take Daisy, for example. Her song, which had been somewhere in the back of her head for most of her life, had a reassuring, marching sort of beat, and words that were about protecting the weak, and it had a chorus that began “Evildoers beware!” and was thus much too silly ever to be sung out loud. She would hum it to herself sometimes though, in the shower, during the soapy bits.
And that is, more or less, everything you need to know about Daisy. The rest is details.”
Anansi boys – Neil Gaiman
