Huh. So it's closer to something like symbiosis in your case, whereas in mine it's... incidental. [He doesn't know how he'd feel about it if the lizard came with both stronger drawbacks and some sort of benefit. Fixating on trying to find some sort of explanation or function for it was one thing, growing up, but how much more frustrating would he have found it if he'd actually turned up an answer?] Haha, not all that many similarities after all, once we get into it. Though I'm glad we can both say that it's not killing us.
