Stay with me on this one as I get philosophical.
Life is like a bridge.
Some people cross it and some people don't. Some people don't like bridges and get anxious when they drive over them. Sometimes there are people fishing from the bridge of life. At the same time, there are others that are sailing under the bridge, going a different way. Sometimes they're going fishing too. Either way it's not a safe place for fish.
You see, the bridge is like a gateway from one state to another, and the water is like reality, and we are the fish, you see?
So there you have it, life is exactly like a bridge, much like the Kemah bridge, where I ran 4 miles this morning.
