Okay so one day, i was sleeping over at my friend's house. It was 10:00 pm and we were getting ready for bed. We were home alone, her mom was at some party at her job. So as we were crawling under the covers, i heard a knock on her door. My friend got up to answer it. I told that it might not be safe, so we hid under the bed for an hour, some one STILL knocking on the door. When it finally stopped, her mom came home. we told my friend's mom about it, and she told us it was probably one of there cats. The next day we learned that there was a robber wondering around her street. it scared me to death!!
