““While — say — the butcher serves a lady who is shopping for five days for her family of fourteen, you must not take advantage of a momentary pause (as you would in France) to butt in and ask if he has any calf’s liver — not because you want to be served out of turn, of course, just to find out whether it is worth waiting. You will get no reply. This is not discourtesy: it is simply due to the fact that you do not exist. You may not be aware of this; you may live in the mistaken belief that you do exist, but you do not. Before your turn comes you are less than a dog. A dog would be noticed and urged to leave the shop. But you definitely do not exist before your turn comes, you are a non-person, you are thin air, a nonentity, a body non-incarnate, waiting to be materialised when the butcher turns his smiling attention to you.””
