Do they catch their hands muttering sometimes when they’re not signing, their fingers whispering to each other or trying to tell whoever that might be at the other end of an arm what they’ve forgotten and must remember? Do they hesitate to go on saying what they won’t have the slightest chance of meaning tomorrow? Do slips of the fingers count against them? Do they practice sleights of hand? Do they slur under the influence of second thoughts or do battle almost helplessly with those quicker to reach conclusions, with interrupters, with careless, heavy thinkers, with ambiguous partners or strangers? It must be easy to babble or go crazy without half trying, but how can lovers hold hands unless they mean to go quietly all the way?
