Indian Spring

Is there such a thing as Indian Spring? A very early harbinger of warmer weather to come. A day when I can run comfortably in shorts. An afternoon when I can sit outside to enjoy a cup of tea. A night when I can crack open the window once again. There are no leaves on the trees, no green to the grass, not even a crocus popping through the debris in my garden, but still, this feels like Indian Spring.
