Yup, Pierre Gilliard said Olga and Tatiana were passionate to each other. As for Tatiana if she lived in our time I’m sure she would have being a great public minister. Tatiana in 1912, when she was a teenager, wrote to her mother:” I hope that Anya () would be nice to you and will not bore you and will not come and disturb you if you want to be alone. Please, dear Mama, do not run from room to room, checking everything was in order...... Good-bye, till tomorrow. Darling, do not worry about the Baby. I'll look after him, and everything will be fine” She talk to her mother in this letter with a maternal and caring tone. And it seems she took her mother role (when Alix is absent) of taking care of her younger siblings. No doubt as Olga and Tatiana grew older, they worked together and took more responsibility towards their siblings(set some disciplines for TMA) and family, and give support to the family in difficult times.
