Ovillejo from the Earth

I found upon the step a puppy’s tooth.
I tell the truth.
Small and clean and white as milk,
Smooth as silk.
A treasure cradled in my palm,
A gift of calm.
Who knew a tooth as mid-day balm?
A small white star, come down to earth:
A tiny sigh, a tiny mirth.
I tell the truth smooth as silk a gift of calm

Note from Allison about the poem: Three rhyming couplets and a quatrain “What has earth given you?”
