Daemons can eat human food just fine and we even have some dishes in common, not that most daemons would admit to that. It's more that daemons don't tend to do something just for the sheer pleasure of it, like have a party or drink alcohol. I've always found that silly and want to try it all. [Yes, even coffee. She'll dislike it, but she's more inclined to want to try it first.]

But really, cookies on trees? Is that even possible?
