    It's true that “A small change can make a big difference” in our life. A better technical term that can well 1 this idea is the “Butterfly Effect”. A butterfly's 2 wings can make changes in the path of a tornado; it may  3  create or prevent a tornado at a certain location.

    The “Butterfly Effect” plays a role in our  4  to a great extent. Small  5  could make a huge difference in our relationships. Most of the time we take things for granted in our  6 relations.

At first I was  18 how just a 10-minute difference initially could add more than 30 minutes to the journey.  19 , the number of vehicles that come out on the road increases more than twice due to that 10-minute  20 and it looks like butterflies crowding on the road. Yes, this is nothing but the “Butterfly Effect”.
