Caution!
Standing in the middle of the path, it glowed yellow.
Its feet perfectly balanced the weight of its body.
Everyone who passed by it, looked.
When they saw it, they stopped. Or they would go around. Many broken bones and twisted feet were avoided.
Those who didn't see it, fell. Or slipped. There were even those who tripped over it.
Anyone who didn't see it was so scared that they had to look to the ground for the rest of their lifes.
Nobody paid any attention to him, there alone, in the middle of the way. Yet he warned of danger, like a harbinger of doom.
It was yellow and in it you could read “CAUTION! WET FLOOR”.
