Sometimes in life, we don’t know which choice is the best. It is usually easier to judge choices in the past, because we know the outcome of the choice that was actually made. Sometimes we have more information now than we did at the time we made the choice. We express this in the proverb “Hind sight is 20/20.” “Hind” is similar to the word “behind,” and in this case it means “the past.” “20/20” is the score a doctor gives you if you have perfect eyesight. If your sight is 20/35, you probably need glasses.
