Rocks!

What do we consider to be one of the strongest things around us in nature? Rocks right? You are my rock, caught between a rock and a hard place, etc. We use them for support to help pick us up, to help balance things when we can not do it by ourselves.

Did you know that rocks are actually quite fragile? You heat and cool one a couple of dozen times and it will actually explode. Funny how something that appears so strong is really so fragile.
