Example sentence: The peculiarities of my childhood, of constantly moving through so many different cultures, of always being the outsider, may have made me extraordinarily self-sufficient, but it had also bred a certain detachment, a sense that the world was a place to explore rather than truly inhabit. This manifested as a kind of shyness, even timidity.
