Answer:
I can ruin your day, or darken your life. And while I'm expected, I'm never alright. I'm bad for business, and worse for your hair. Wherever I am, there's something not there.
I have legs but never walk, I may have flowers but no soil, I hold food but never eat.
Soldiers line up spaced with pride. Two long rows lined side by side. One sole unit can decide, if the rows will unite or divide.
All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard.
You heard me before, yet you hear me again, then I die. Until you call me again.
I'm the source of all emotion but I'm caged in a white prison.
