That water drop won’t last long. Soon the friction won’t be enough to prevent it from going down the leaf as the day warms up.
The same thing is true for lots of things. They don’t last long and eventually change occurs. One example might be current oil prices. The Trump administration and OPEC might keep screwing around long enough with trying to control countries and prices until the cost of oil ripples through the market in terms of increased costs for everything that moves, and it triggers a global recession, assuming it actually isn’t a depression. Hmmm, image how that could impact the results of the next elections.
