I ws only 6 then. there was a new flyover built in our nearby area. it ws rare then in our country. so, i ,my mother nd my brother Joy went 2 take a walk on it. it ws morning . i nd joy were vry happy. i didnt think about nothng but running across it.but there were lots of vehicles .so, ma kept an eye on me. but no use. suddenly, i ran across it 2 look at da bottom from another side.
