I actively try and make sure that I'm not giving away anything that could make it easier to trace me, or whatever. Because it all adds up, you know. Your name is William? You live in Ohio? Parents are dead? You have six dogs and a little sister who has terrible allergies? Right, so anyone bloody-minded enough could use all of that to find you. And it may feel unlikely that anyone would give a damn, let alone go through all the effort, but lunatics don't get tired. Not that it's just about lunatics...
So yeah, I don't tell anyone anything. Information can be weaponized. I'm no different in real life, either, because that's where it really counts.
