We all know that depending on the angle of the sun, shadows can be elongated or shortened.
Sometimes shadows can multiply or fatten or become the focus. You have to look carefully to see that.
Check out these two images of evening shadows caught on a cloth interacting with the form behind. Nothing simple about them.
In this one, the shadow seems to walk away from the actual person casting that shadow.
In this one, the shadow seems to be holding the cloth rather than the other way around.
Keep your eyes open. Notice shadows!!!!
