Why so fickle?

Ever so fickle
Why must there be somethings easily broken?
Twigs
Glass
Bone
Hearts?
Why must we be so fickle
Subject to the ever so slight change in tune
Why are we so malleable?
allowing ourselves to be molded and hardened....
....only to be broken
Why are we so unstable?
Is it in our nature?
Do we choose to lose?
Or do we look to win but accept loss as an inevitably?
Why so fickle?
Ever so fickle
