I immediately sprinted to my room and hid... The knocking has stopped. But i don't know if the front door is still safe. Alex said he has good news and bad news. Good news is that he his closer now. Bad news is. He's out of fuel... There isn't any gas stations near him. All the power is down. and all of the nearby gas stations are electric gas pumps. He said he was 8 or 9 hours away. I decided to not go outside this time... At around noon i heard someone screaming.
