We had a kind of pity for each other; we were both afflicted permanently with a feeling of sad helplessness because we were unable to make each other happy in this way. But nothing stopped us from choosing other partners. We did not. That I did not, isn't surprising, because of that quality in me I call lethargy, or curiosity, which always keeps me in a situation long after I should leave it.
