I find if there are more than 3 people in the room at once, I have a hard time following the conversation(s), because the sensory overload overwhelms my ability to process the incoming data and I can't even understand what people are saying about half the time (as if they were mumbling, but they aren't).
I have to keep leaning in and asking them to repeat themselves, as though I were slightly deaf, but it's not hearing that's the problem, it's my brain unable to interpret what I'm hearing fast enough for me to comprehend it.
