Here's part of a Robert Frost poem I found this week that made me smile. I understand completely his sense of not wanting to speak (or breathe) and spoil any bit of warm weather that comes our way in early spring, assuming it comes back that is. :)
The sun was warm but the wind was chill.
You know how it is with an April day
When the sun is out and the wind is still,
You’re one month on in the middle of May.
But if you so much as dare to speak,
A cloud comes over the sunlit arch,
A wind comes off a frozen peak,
And you’re two months back in the middle of March.
From Two Tramps in Mud Time 1934
