Hmm. I do think I'd make a good, unusually benevolent, eldrich god. On the other hand, I still miss my beta fish that died 5 years ago. No telling how I'd react to the rise and fall of a spider family line, dozens of generations in length.

Tarantulas are cool, but I'd worry about dropping it. I know they typically don't bite, and that their bites aren't dangerous. Still, I don't know if I could relate to it positively after that. It's not rational. I've gotten mild dog bites and cat scratches from pets playing too rough, and those are much more dangerous. Tarantulas still pas the cuteness test, but I think the spider bias affects them more than jumping spiders.

I don't think I've ever been uncomfortable having a jumping spider on me unexpectedly. It's fun to watch them hunt. Watching the retinas in their big eyes move to track things is fun. It makes them seem more like adorable cartoon characters.
