Life is like a box of chocolates keychain

Do you remember the movie dialogue, "Life is like a box of chocolates... you never know what you're going to get" from the movie, "Forrest Gump"? If so, you are experiencing a Mandela Effect. Currently, that movie dialogue is and always has been, "Life was like a box of chocolates." That small change from the word "is" to "was" presents us with a Mandela Effect that hints simultaneously at quantum uncertainty: We can know some information, but not have certainty about all information; and quantum retrocausality: events in the present or future can influence past events.
