to test the limits of my abilities

I dunno it's funny when I grab my dog's tail and they start wagging it even faster, then start chasing my hand around. It's funny

I'm just a spectator. I would never touch anyone's tail without their consent.

simple! it's because sharks are smooth no matter what way you pet them

I was just doing it to a bunch of people cause i thought it would be funny. But also I just have a lot of stupid trivia in my brain, like that blades fundamentally can't cut if you don't let the blade slide, which is how half-swording works. So again, if someone hold yours firm enough it can't cut them.
