Can you guys also not hear anything when there’s background noise?

Not a goddamn thing

Noup, it all melts together into one indistinguishable noise. Sometimes it's better, sometimes it's worse.

When a person who I've known for longer time is speaking loudly and clearly towards me and I'm ready to listen, then i can mostly understand what they're saying, of course if the environment is somewhat normal.

But if it's a new person, with a bad speaking mannerisms, that's already enough to make whatever they're saying completely incomprehensible, even in a quiet environment. Add in some noise and there's even no point to try to understand them.

Initially yes, but I'll get overstimulated trying to focus on a person's voice in 2 seconds

I've never been diagnosed with anything but I had an interesting / uncomfortable experience the other day, went to a cafe with family, we were sat close to another table of 6, everyone was really loud and I felt totally overwhelmed, I noticed everyone on our table looking at me after a couple of seconds and I suddenly noticed the waitress had been speaking to me! Didn't hear a word she said until I focused on her. Its the first time I've experienced my brain just melting all the noise together.

So embarrassing to stand in front of a door, ready to knock, but you can't because someone's making noise in the hallway and you won't hear the "come in" through the door now.

I’ve been accused of ignoring people quite frequently. I didn’t even know this was a thing. It’s always in a chaotic situation where my attention was elsewhere but people would be talking to me and I had no idea and I got accused of just being rude. I would never ever do that. I need to go look this up.

Wait wait wait one goddammed second. Is that a thing: hearing someone speak, saying "what was that?", then a moment after they start speaking, you suddenly know what they said the first time?

I discovered I had ADHD in my 30s and it was life changing. If this is another thing, then I'm in for another life changing discovery in my 40s.

I just got the joke and I piss myself off doing this constantly. Maybe it's because our thoughts were interrupted and it is our way of changing gears.
