These are days of high contrast: 70 degrees and cherry blossoms one day, 30 degrees and sleet the next. Are those petals or snowflakes?

Weather like this reminds me of what I should always remember but almost never do: Enjoy what you have when you have it. So much is out of our control.

I thought of this yesterday when I took a quick stroll around the block at lunchtime. It was warm with a balmy breeze. The jacket-less turned their faces to the sun. The al fresco diners ate salads on round, wrought-iron tables. A lone Tai Chi practitioner balanced two red balls on the top of his arms, slow-mo juggling.

We all knew the forecast. No lamentations for what was to come. Just joy at what we had right that moment.
