I think that Olga and Xzenia had different personalities were not very close, and had different ideas about what they wanted out of life, especially after the Revolution. The reason they led different lives, was different circumstances, and that they wanted different things. I agree with those who say that Olga was a fairly down to earth person. If you read her biography, you agree with this. I think Xzenia was more imperial, but then, I don't know much about her.
