i never get tired of when i get to watch how someone's fears and insecurities manifest through how they carry themselves and act around others. great psychoanalysis material. but also it's quite admirable when someone isn't ashamed of showing their flawed nature and human vulnerabilities, which is the main reason why i'm drawn to it. my second favorite thing would be development, even just the tiny ways someone changes behavior or perspective. idk it's like studying a plant grow or an animal transition
