I lived on top of a wooded hill in a trailer with 3 roommates. Everyone around left to go to a halloween party, and I went, but got there and realized i'd forgotten my costume. As I walked back up the hill, i heard some people say, "She's going back. Let's follow her."
When I got to my house, 3 big guys and their girlfriends were going through our stuff and taking things out to their truck. I was afraid they were armed, so I didn't stop them, and even helped them move stuff. I couldn't get to a phone without their noticing, so I decided to be mildly irritating until help arrived. Finally a pretty big guy i know got to my house, and he took over, telling people not to take things, but they didn't really listen. I went back to my room and saw a little asian girl trying to take a laptop, so i picked her up by the arm and handed her to one of the girlfriends, who was wearing swiffer wetjet pads as shoes. I started talking trash to her, and ended up getting in a brief scuffle before I ran through the house, out the front door, and down the hill to get other people to help us. On my way down the hill, I encountered everyone coming back from the party, and started yelling "911!"
They went up to the house and made the people leave.
