Funny, it sounded like rain outside - on a clear sky morning. How does that work?
Yesterday we had snow that turned into rain, then sleet. Then an overnight freezing that turned all the trees to crystal. This morning's sun turned those crystals into water droplets falling from the mature trees around our house. Exactly like the sound of raindrops.
I hope that yesterday was the last snow for this winter season, but I'm not so sure. The trees are weeping because they are done with winter, too.
