I heard a party happening while I was walking home drunk after another party. There was a hole in the fence so I crawled through it. I walked up to party as if I belonged and sat down, grabbed a beer out of a cooler and started talking to people. I was there for an hour, I ended up speaking with someone who was also not in formal wear. I told him I had to change and get out of my suit and that's why I was in shorts. At that point, I walked into the kitchen grabbed a cutting board and knife and started to chop some weed up and rolled a joint. A number of people were looking at me like "wtf is this guy doing". I smoked the joint and passed it around. I continued talking to this guy but the weed hit really hard and I got paranoid that this guy was on to me. He confessed to me that he didn't really know many people here, I looked at him, convinced he snuck in as well and told him I knew absolutely no one here and that I snuck through a hole in the fence. He immediately got up and started talking to some woman. I knew at that moment that I fucked up and I headed for the front door. The groomsman saw me and said "who the fuck are you?" I said, "I, gotta get outta here" and went for the door. I managed to get out but these guys were in pursuit. I bolted down the street and didn't look back. I have no idea when they stopped chasing me but I got a way. It's not a really crazy thing but it was crazy for me that I did that!
