If we ant to get all analytical… this sign really does work but not for the obvious reasons. It’s interesting how it’s made up. If you’re ASD, you don’t even realize that a cue was given because you’re interested in the design.

Then, you figuratively realize “oh shit, that’s a cue…” and have to sort it all out while being irritated that someone couldn’t just make the design mean what it’s supposed to mean.
