Yesterday, I got hurt in a accident in the supermarket besides our school. I was just going around the corner while a strong man crashed into me with his shopping cart. It was impossible see each other before the accident because the corner was very dark and the lights didn’t even work. What’s more, the floor was very wet because it was rainy yesterday. So I fall, got knocked out and was serious hurt. Although the supermarket paid for the accident, but I still want to give some advices to the supermarket. Always get the lights checking at least once a week and make sure the floor is dry all the time, that would help make the supermarket a safer place.
