Sembawang, 49 km. My crank does what it's designed to do: crank. It also creaks, which sounds like trouble. I'm told the bearings are on their way out. A few km later, the creak goes away. Why? Do the bearings warm up then bear up to the pressure? Whatever the explanation is, the sound goes away. I know it'll come back. And, it'll go away.
Good things come in life. And they'll go away eventually, some sooner, some later. Bad things come in life. I know some will go away. Or, at least, the memory will fade away. Accept the good. Accept the bad. No exceptions.
