She walked rather quickly; she liked to be active, though at times she gave an impression of repose that was at once static and evocative. This was because she knew few words and believed in none, and in the world she was rather silent, contributing just her share of urbane humor with a precision that approached meagreness. But at the moment when strangers tended to grow uncomfortable in the presence of this economy she would seize the topic and rush off with it, feverishly surprised with herself-- then bring it back and relinquish it abruptly, almost timidly, like an obedient retriever, having been adequate and something more.
