Accident

Accident is happened unexpectedly.

Yesterday I was standing on the train home with my colleagues. As soon as the train pulled out, the train swung. At the same time a man, not tall and a little fat, standing in front of me learnt to me. Althought I held a pole beside me, I couldn't keep standing. When I almost learnt back, one of them helped me. She supported. I didn't fall down. I've relieved. But I had a splitting headache.
