They're not holding hands because they're in love or anything like that. It's to prevent the other from floating away, so they can stay close to one another. It's a survival thing. Not love.
I know what it really *is*. And frankly, I don't care.
I didn't seriously think the otters were in love (animals don't know what love is anyway), but it *looks* cute. It *looks* like they're in love. I could give a damn if they actually are.
