I have to decide what familiar saying or proverb is hidden in two of these formally written statements. Then I need to write it in informal language.

1. A single pass of the needle in sewing will oftentimes prevent the necessity of nine such passes.

2. The individual who is the final one of a group to express his amusement through appropriate vocalizations is generally the one who expresses his amusement for the greatest duration.

1. A stitch in time will save nine.

2. He who laughs last laughs longest.

1. The more stitches you make with one pass of the needle, the less times you'll have to do it again.

2. The person who laughs last, laughs the longest.

To find the familiar saying or proverb hidden in these two formally written statements, we can identify the main message or underlying idea they convey.

1. In the first statement, it suggests that doing something right in the first try can save a lot of time and effort later on. This aligns with the proverb "A stitch in time saves nine," meaning that taking immediate action to address a small issue can prevent it from becoming a bigger problem.

To rewrite this in informal language, you can say: "If you fix something right away, you won't have to fix it again later."

2. The second statement implies that the person who laughs or reacts last tends to keep laughing the longest. This reflects the saying "He who laughs last, laughs longest," indicating that the person who has the final and most recent response or reaction often has the most satisfaction or amusement.

To express this in informal language, you can say: "The one who laughs last, laughs the hardest."
