There’s nothing wrong with a fun selfie, unless you’re taking a selfie with a dead body or while covered in blood. Though the ICU may have some excellent lighting, it's meant to care for your health, not your narcissism. For some reason everyone thinks people want to see their gore-soaked, tube-laden selfies into the world. Selfies in hospitals aren’t wrong on a fundamental level, but trying to look sexy in a hospital gown is like posing in the middle of taking a number two: who wants to see you at your lowest?
No one enjoys being in a hospital, and when you post a hospital selfie you force the world to go to the one place they hate while you show off how good your bum looks in a paper gown. No thanks.
