For better or for worse than what it was before
My sudden appearance can cause stress and alarm
I can sneak and surprise, or drag on for days
Though I promise you now that I mean no harm.
Your opinion of me is varied
Depending on how I act
Preparation makes me no easier to endure
And that is a fact.
However, I may bring excitement
I can form something you enjoy
A flash of improvement
To play like a toy.
Yes, I am a mystery
Yet always drawing near
Nothing can prevent my hands
Or stop the work of my gear.
