The trees are sure of themselves now. Even the most timid have leafed out. The only outliers I see are the crepe myrtles, and I get their reticence. They are in glorious bloom at the end of summer; they need to bide their time now.
Leafing trees mean a canopy between us and heaven. They are an aural presence, something for the wind to blow through before a storm.
And of course, they also mean shade. At this time of year it's baby shade. Not the deep cool gladness of June, July and August. The shade of May is a winsome thing, still finding itself.
Come on, baby shade! You can do it!
