The Horn And The Saw
I just spent 20 minutes sawing something in half that I thought would take me about 2 minutes with a brand new hack-saw blade. It was a ram's horn:
It was a present for Hector to chew on but it was so heavy, he couldn't carry it around very far - hence the sawing. I learnt something today - nature intended these things to be unbelievably solid - and nature did not let the ram down.
When you need a job done properly, you will usually find that nature has all the answers and that's why stuff happens the way that it does out there.
