What if rocks are soft, but they harden when we touch them?

For some reason the thought disturbs me:

then they would be called "P**ises" lol

dicks f**king censorship pe nis is in the dictionary wtf

that doesn't happen. I've seen robots pick up rocks and the rocks are so hard the robots always remark about how the hardness of the rocks is really, really hard.

well maybe they tense up when ANYTHING touches them

impossibly impossible

Then how come they're hard when I poke them
