Actually, the first time I got Shuang Shuang, she also gave me this haughty look downstairs. However, it all changed when we went into the room.
True, she was not into speaking french the first time, but her attitude to please otherwise was outstanding. After a few RTFs, speaking french came naturally. Certainly she is one of those where she treats her regular much better.
Honestly, sad to hear she is going back, but I would imagine that if that was true, not really worthwhile to 'invest' in her, unless you are a regular already. Speaking of which, better plan for a few farewell visits.
