#6I was once asked what drugs I had taken, which confused me because I had taken none. A mirror inspection revealed that my pupils were hella dialated, for no apparent reason.
"On command" seems a plausible stretch from "spontaneously for no reason."

Indeed, i can do this too. I stopped after they diverged into different sizes (one being enlarged and one being shrunk), as I became a bit worried it was perhaps dangerous. They were restored within a few minutes, though.
