Hindsight is imperfect, at best.

Hindsight, a.k.a. "Monday morning quarterbacking", is a less than perfect vision.*

Even when you are the one who was there: what you saw is unique, your singluar perspective, and what you remember is interpreted by your mind's eye.

... more later ...

 

"There is no quiet without sound."

..., ..., ... later: For a clear vision ahead, walk backwards.

 

 

REM: "What if" never was and will never be.
