“There are times now, and my life has changed so completely, that I think back on the early years and I find myself thinking: It was not that bad. Perhaps it was not. But there are times, too—unexpected—when walking down a sunny sidewalk, or watching the top of a tree bend in the wind, or seeing a November sky close down over the East River, I am suddenly filled with the knowledge of darkness so deep that a sound might escape from my mouth, and I will step into the nearest clothing store and talk with a stranger about the shape of sweaters newly arrived. This must be the way most of us maneuver through the world, half knowing, half not, visited by memories that can’t possibly be true. But when I see others walking with confidence down the sidewalk, as though they are free completely from terror, I realize I don’t know how others are. So much of life seems speculation.”
