What is your first memory?

This may not be the first one but the most significant one.
It seemed to be a very ordinary day. I was nearly running down the street like other business people in a hurry. Suddenly I unconciously stopped. There was a small white butterfly. It was flying peacefully and it passed in front of me. I've never seen a butterfly in that crowded and poluted region of the city. At that moment it did not just stop me in the middle of the street but also it stopped me in the middle of my life. Made me take a break and have a look at.
