Answer:
I grow where no flower grows, where no light touches the walls, up or down, that I don't care, was here before people were.
I can be moved. I can be rolled. But nothing will I hold. I'm red and I'm blue, and I can be other colors too. Having no head, though similar in shape. I have no eyes - yet move all over the place.
As light as a feather, but you canβt hold it for ten minutes.
As a whole, I am both safe and secure. Behead me, I become a place of meeting. Behead me again, I am the partner of ready. Restore me, I become the domain of beasts.
Often held but never touched. Always wet but never rusts. Often bits but seldom bit. To use it well you must have wit.
Almost everyone needs it, asks for it, gives it. But almost nobody takes it.
