"That's - how magic works in my world. You wish or pray for things, and sometimes you get them. I've heard it's different here, though. But I haven't made it any non-magical way either, and I feel like I'd remember doing that, and I have no idea who you are and no way of getting little paper circles to you if I made them, so 'made a weird wish and forgot about it' is at least slightly more plausible."
