Fleeting Freeze

The hoarfrost reminded Philadelphia of her granny. The Queen Anne's lace was puckered to kiss the cold morning. Melting drips were splashing loudly. 
Hoarfrost was "whore frost" for years until Philadelphia read it in an L. M. Montgomery book. Whore frost made sense because it's a shallow, fleeting and forgettable freeze. Hoar is just an archaic word for grey. Proving again that, historically, we didn't have time to moon around with metaphor.
