I have a neuromild friend who, when I am on a rant because the world works the wrong way, or explaining something in detail that the milds probably don't care about, very politely holds up a little sign for me.

It's like, "Hey friend, this is a 'tism."

They've never stopped me, never cut me off, never sighed in exasperation that the autistic guy is at it again. Just a little note that whatever I'm on about is neurospicier than the milds generally like.
