Just an hour ago, someone wrang my mom's doorbell at home. Thinking it was me, she opened the door and right in front of her stood a young 20-ish looking chinese guy with spectacles carrying a knapsack. He took 1 step in and my mom stared at him wondering who he was. Within a split second, she realised he was pulling out a long knife from behind his bag. She screamed and the guy took a step back in shock as my mom quickly came to her senses and slammed the door shut. The guy ran away. He was probably an amateur who has never robbed anyone before. But i'm glad my mom wasn't his first victim & that she's safe and unhurt. Please lock your gates/doors /grills before u sleep tonight. Good night.
