I may or may not be biased

you know how. You need someone to just randomly toss you into a pool. Your instincts will kick in and you'll know... or you'll panic and you'll drown, whatever. I guess you could learn with the edge shark technique, but that's only going to get you so far.

Given that I already almost drowned once and needed someone to fetch me when I was already unconscious, I'm not trying that again.

I've picked from memes that right is Ijiranaide, Nagatoro-san, but idk about left.
