The other day I was sitting in my neighborhood Starbucks surrounded by the chatter of conversation and people hunched over their laptops or newspapers.
At one table, however, something remarkable was going on. A woman was sitting in an armchair, her laptop perched on a table in front of her. She was having an exuberant conversation — in sign language.
Not a sound came from her except for an occasional guffaw, but her conversation was so animated you almost felt you could hear it.
