When you’re in the midst of a conversation with someone who is blind, make sure to let them know if you need to step away for a moment. If you don’t and they don’t hear you move, they will keep talking as if you are there. That makes them look unaware and silly.
I know it’s tempting to do this because anyone who can see communicates as much with gestures, nods, pointing, and so forth to complement or replace speaking. But because your blind friend, family member, customer (in a store) or business client can’t see you, they must depend on your words to know where you are.
With that said, if pointing is natural for you, speak in specific directions. “Over there,” “here,” and “there” don’t help someone who needs to know where you are indicating and what you want them to know.
