Don't write stage directions. If it is not apparent what the character is trying to accomplish by saying the line, tell us how the character said it or whether or not she moved to the couch isn't going to aid the case.
David MametThe basis of drama is... the struggle of the hero towards a specific goal at the end of which he realises that what kept him from it was, in the lesser drama, civilisation and, in the great drama, the discovery of something that he did not set out to discover but which can be seen retrospectively as inevitable.
