Addendum

[ladynox25]

I can't help thinking, whenever I fly, of the following from Both Sides Now by Joni Mitchell, which is, incidentally, one of my favorite oldies songs of all time:

Rows and flows of angel hair
And ice cream castles in the air
And feather canyons everywhere,
I've looked at clouds that way.

But now they only block the sun,
They rain and snow on everyone
So many things I would have done,
But clouds got in my way.

I've looked at clouds from both sides now
From up and down and still somehow
It's cloud's illusions I recall
I really don't know clouds at all.
