She always surprises you this way, by knowing more than you think she does. Louis wonders if they're calculated, these little demonstrations of self-knowledge that pepper Clarissa's wise, hostessy performance. She seems, at times, to have read your thoughts. She disarms you by saying, essentially, I know what you're thinking and I agree, I'm ridiculous, I'm far less than I could have been and I'd like it to be otherwise but I can't seem to help myself. You find that you move, almost against your will, from being irritated with her to consoling her, helping her back into her performance so that she can be comfortable again and you can resume feeling irritated.
