Nothing much. So first off, I don't think permission would be the right word, personally, that I would use. Because when you say permission, that's kind of like, you know, someone having ownership over something, or in this case, someone. Yeah, true. And secondly, I would say that's only reserved for, like, really close friends. You know, like, in this case, this guy and Zach were really close. But if it was someone that Zach kind of, like, knows, but they don't really know each other, then he doesn't have, you know, he doesn't have to tell Zach about someone that he used to get in the past.
