Ahhhh. Nature can teach us many lessons, can it not? Let's take the clouds for instance... Cumulus, Stratus, Cirrus, Nimbus... and many combinations of those named. Regardless of the type, name, or stratospheric circumstances... the clouds will never ever look the same... ever! Much like life. We can name those circumstances we think will take place... but do we really ever see the same thing over and over. It's just different somehow... this time.
