On YouTube. You get that rush of dopamine. You go to check out your hearted comment, but there's nothing there. They in fact DON'T like your comment and probably never did. Just hit the like button by accident. So much so that they made sure to unlike their like and then you're like "No! But what about my dopamine hit?!?!" And then life is like "Fuck your dopamine hit! Get off the internet fool! Muahahaha!" I hate it when it does that..
