Step 12: Cherish Your Weighted Companion Cube - Step FOREVER
LOVE YOUR COMPANION CUBE, not like it's hard.
Relish it's company and keep it handy.
That is what it's for.
I didn't invent the Weighted Companion Cube, the genius's at Valve did :)
If you hurt yourself, it's not my fault. It's also not the fault of your Companion Cube. It's your fault.
