     One Sunday night, a teenager, Rory Campbell heard noises next door to his home in Bonita Mews, off St.

Asaph Road, Brockley. When he went outside, he saw his neighbor climbing out of a front window of his

second floor flat. He then saw the man covered in black soot (黑灰), tying himself to the window, shouting

for help.

     The 15-year-old boy called the fire brigade( 队) and tried to calm the neighbor, who is in his 30s, until

firefighters arrived. Rory said, "He was shouting 'help me, help me, get a ladder, get a ladder'. He was a bit

wild. I didn't have time to think. I just tried to calm him by telling him the fire brigade was on his way."

     Rory was told by the man that the fire had been caused by a candle falling over. Fire crews from New

Cross, Peckham, Lewisham and Forest Hill rescued the man by ladder and got the fire under control within

minutes of arriving. He was taken to a south London hospital where he is still recovering from smoke

inhalation. (吸入)

I do feel good that I helped save his life."
