Its meaning is clear:  Come here.  Come over HERE.  Now -reach out.  Catch a little of the magic dust that has spilled across these tender folds.  Carry it, unawares, in the ridges of your fingers and spend it somewhere far away, rubbed against a sympathetic branch, which is waiting for just this intrusion.

It is not accident that we use these brazen delicacies to speak for us.  How could we admit such things to ourselves, any other way?
