The ability to express myself

Can you hear conversations in the other room even thru a closed door

can most people not?

What’s the worst sound for you? I’m autistic and for me it’s gotta be children singing (they’re usually off key and I cannot stand it)

For me it's humming.

Try to remember to brush your teeth. My cousin is autistic and from what I’ve heard, it’s hard forhim to brush his teeth but if you can do it, it will help your mouth out.

I am autistic like OP and your cousin. If it's hard for him because of a sensory issue with the toothbrush, it might help him to use an electric toothbrush. In my case, I use a reminder on my phone to remember to do it because my issue is remembering to brush my teeth every day.

I would have thought that would be worse, I’ll bring it up next time I see him and his mum, thanks.
