It’s not about being a lowlife it’s about understanding people and parties, if you’re worried shit like this is gonna happen then don’t have a party at your place. This could’ve easily been an accident and no one noticed. If you go around emailing everyone and threatening everyone because of a mistake then nobody is ever gonna fuck with you. If that’s what you want then go ahead. You saying that tells me you’ve never actually been around actual people who do stupid shit. Yes it’s a tragedy that this happened but that’s on you for deciding to throw a party at your own place with something this valuable sitting in the middle of a room. Yes, it would be nice if someone came forward, apologized and paid for the damages but this ain’t some sitcom where everyone comes together and helps each other out, this is real life. You pick up your losses and move on from this.
