Her approach in other areas is also unusual. For example, in her role as a governess she has found that her charges' reading progress has been greatly enhanced by using interesting books which are slightly too difficult for them, and which therefore present something of a challenge. Parents have reservations about her choice of General Tacticus' "Campaigns" as a reader, since it may be argued that children under ten do not necessarily need to be able to spell 'disembowelled'. When other adults point out that children should find these exercises too advanced, Susan acknowledges this, but points out that she hasn't told the children this and so far they seem not to be bothered about it.
