Staying quiet doesn't mean I have nothing to say; it means I didn't think you are ready to hear my thoughts. (And you're making it pretty clear that you are absolutely not open to discussion.). Ask nicely.
this is truly heartbreaking for me because when I'm quiet is when I need to be noticed, and feel at my most alone. Take notice of the brilliantly shiny people if they are quiet or smaller or missing, seek them out, they may need to be found again.
