This is a story around the famous idiom- A stitch in time saves nine. Sid was the energetic, young lad who had a knack for speed, race, timing etc. ... One day, in the mad rush to win the race, he met a small accident with a car but he was quick to brush it off casually. A few stitches here and there and he was all fine.
it's a proverb saying that if you sort out a problem immediately it may save a lot of extra work later.The phrase basically means it's better to solve a problem right away, to stop it becoming a much bigger one.
