Got one time, a chinese man a round his forties quite plump one
ran to my door. It was around 8+ in the morning, my mother lying on
the couch watching and I still brushing my teeth.
Metal gate was locked but wooden door opened. The man was like
in a hurry and kept shaking my metal door damn hard until I yelled
at him.
Then he said, "sorry wrong unit." Then ran away liao. Mom told
me not first time liao. Previously was a skinny man.
So at night don't anyhow open door. Besides, my experience with
calling the police, they always come quite late lah. By then I
think war over liao. So it's important that we learn how to protect
ourselves.
