I was inside my house which is in a friend's claim, when suddenly, a stranger came in. He saw me and immediately left the house, but I followed and trapped him by spawning onto him. He obviously didn't know that he could escape by sprinting, therefore I started ...interrogating him about what he was doing inside the claimed house. I bet he was scared at that moment, since I was wearing my rather intimidating (hehe) bear cape.
This guy seemed to be quite noobish and typed :fs 0 into the chat twice, and rejected my offer of adding him to my kin list three times. I told him to accept it to prove his innocence, so I would know who he is. I got ignored, he said he got no invitation or anything. Also, the intruder claimed to have been rowing when suddenly he got teleported inside my house (though I believe I heard the door-opening sound while inside, but not 100% sure). I'm not sure if he took anything, since he didn't really have time to... but I could be wrong. There's so much shit in that house, I'd be glad if he took away some of it

So, here's a nice little story taken right out of the life of a Hearthling.
P.S. If you're that intruder and didn't have trespassing, I'd be interested in how you could enter that house on a claim. I'm usually generous about giving away things, but please, ask me before doing such foolish acts.
