In those days, we imagined ourselves as being kept in some kind of holding pen, waiting to be released into our lives. And when the moment came, our lives -- and time itself -- would speed up. How were we to know that our lives had in any case begun, that some advantage had already been gained, some damage already inflicted? Also, that our release would only be into a larger holding pen, whose boundaries would be at first undiscernible.

The next day, when I was sober, I thought again about the three of us, and about time's many paradoxes. For instance: that when we are young and sensitive, we are also at our most hurtful; whereas when the blood begins to slow, when we feel less sharply, when we are more armoured and have learnt how to bear hurt, we tread more carefully.
