Time Blindness is the inability to feel time passing or accurately estimate how long things take. You genuinely believe you can shower, get dressed, make breakfast, and drive 30 minutes in 20 minutes total. You look up from a task and three hours vanished. Or five minutes felt like an hour.
It's not about laziness or disrespect. Your brain literally cannot perceive time the way neurotypical brains do. Time is either NOW or NOT NOW, with very little granularity in between.
