Traveling down any river, there are twists and turns aplently. It's rare that there is a straight course for long. What's around the bend? You never know until you get there because trees always border the banks. You might get a peek or hear some sounds, that's all.
Thoughts may abound as to what lies around those upcoming bends, and you might imagine what's there from what you have seen before, but you never really know. You might pass under a bridge for road or train, or there might be a footpath alongside. Animals might line the banks, or there might be some people. Will they be friendly? Hostile?
The river might for a time get very shallow and almost unpassable, as a sandbar blocks the channel. You might have to carry your craft across the obstacle. Then there might be rocks or rapids or waterfalls. Danger that causes you to abandon the river for a while or even permanently and set out on land.
Life is like that. You never really know what is going to happen next and if you've been around awhile, you have already faced many, many situations that were unexpected and caused you to change course.
Will today be any different?
Change will certainly occurr. It is all on how you handle it. Acceptance or resistance are your only choices because change, like the weather, always happens.
