Our lives are so important to us that we tend to think the story of them begins with our birth. First there was nothing, then I was born…Yet that is not so. Human lives are not pieces of string that can be separated out from a knot of others and laid out straight. Families are webs. Impossible to touch one part of it without setting the rest vibrating. Impossible to understand one part without having a sense of the whole. – Vida Winter
