Joyann, I actually think that Tatiana has the best example for her younger sisters. Olga she is also a good example too, but I think Tatiana would have a better relationshipw ith her younger sisters. Olga was very, independent and caring also like her sister Tatiana. But, perhaps in my opinion she was not too sociable as Tatiana was. Remember that Tatiana was refered to many by the governess becuase she usually took care of her younger siblings and Olga did not even mind for Tatiana to be the governess.
