In use since the mid-1600s, the origins of this expression are unclear beyond the obvious imagery of someone who is a bit of a fantasist (having one’s head in the clouds is clearly impossible – or at least it was in the days before aviation!). ( source )

(For Tuesday May 27) I love clouds.  Particularly when they looked  brushed across the sky or when they are plump and clump together. I love it when they are tinged with the colors of a new morning sky or with the close of a day. Clouds prompt gratefulness in me because I am reminded of the heavens and of the greatness of who created the heavens.
