Hiking to the hilltop
 To get a better view,
 I found myself in clouds
 That edged the sky of blue.

Standing upon a cliff,
 (How high? I cannot know,)
 I doubt cloud would catch me,
 If I'd let myself go.

But it looked so fluffy,
 Like it could bear my weight, 
 But then the sky 'd looked clear
 From down the valley strait. 

I guess the moral is:
 One just can't trust the sky;
 If you leap into the clouds,
 It's certain that you'll die,
 & when you think the sky clear 
 You may be denied.
