I'm on holiday in Florida until the middle of January so it will be a little while until I get back properly to AppleHouse but in the meantime here's a poem by a poet whose words always speak to me very loudly:
They lie under rain in a field.
are like this as well—
like a painting
hidden beneath another painting.
An unexpected weight
the sign of their ripeness.
Perhaps her words will inspire you to write about something hidden, something that doesn't reveal itself easily but which rewards us when we do notice it.
