Yesterday morning, I was surprising to hear that my best friend Allee has been

hit by a car and was in hospital. The other day when he was going to cross a street,

he was such careful that he didn’t go until he saw the traffic light to turn green. But

hardly had he got to the middle of the street while he saw a car suddenly appear on

his right-hand side and come directly towards them. It was too late for Allee to

escape. He was hit by the car or was thrown a few meters away. He was sent to the

nearest hospital immediately and had operation. When I went to see him, he was

out of dangers but still looked pale. I sincere hope he will recover and return to

normal as soon as possible.
