Shitty things happen sometimes. Like someone shitting in your head leaving you to clean up the mess, driving you nuts in the process.
Damn, just hate being told to act like a sheep. To be told to simply walk around the rock... But anyway that's one way of dealing with (brainless) rocks. Just walk around it and keep going. When you look back, the rock is smaller and smaller, you're far down the road, and the useless rock is still there, at the same place, doing exactly the same thing. (Nothing, of course. What does a rock do?)
