What I Actually Am

When I was sturdier I'd talk about how certainly we all will die.
Eat shadows, bury candles, die.
When I was sturdier I thought:
"So what? I am forever mountainous!"
I bravely said:
"No death of any kind could matter to my mountain mind!
Come years, come surging, I am tall!"
When I was "sturdier" I was secretly scared,
And the fear was blinding.
As you can see, I am no rock.
As you can see, in mountain wind
What I actually am is thinning clouds.
