cross an airport boarding area. Toward another man yapping loudly on his phone: a lawyer discussing a slam dunk case with an underling.
The blind man lifted his iPhone and pointed it toward the noise. In his outstretched hand he held a letterpress printed card. I saw the message:
I am blind. You sound like someone talking too loudly on your mobile device. Please do not be alarmed. I am taking a video. I am making a documentary of people who do what you're doing, in public. Bless you for appearing in my movie. Thank you truly.
