I found this right near the coffee table. I recognize it as Olya's handwriting:

It says, Christmas greetings!

There is kindness in the very name of Christmas. There is joy in every clang of merry bells; there is peace on every hand, on see, and over land, and good-will in every wish of "glad Noels". There is little in the words that I am saying. But the wish that they convey is most sincere. May your Christmas Day be bright, and your troubles ever light, and joy attend you through the coming year.

Olga

That is very sweet of you, Olya! Thank you very much. 

This is also the end of the Christmas Fast,* lasting from November 15 to December 24.

All OTMAA's birthdays have passed, although I have no idea when mine is. 

"Don't worry, we'll pick a day for you. Your name is Anastasia, correct?" Mashka asked.

"Yes." I replied.

"Her feast day is December 22. How old are you?" Tati joined in.

"I have no idea. I barely know anything about myself, let alone when my birthday or my real name." 

"Was für eine Schande." Tati said. "What a shame."

"I thought you only spoke German to your mother." I noted.

"We like to practice, right, Mashka?"

"Da. (мы делаем) my delayem we do. We like speaking in English, Russian, German, and French. That is why we have tutors for each subject." Mashka explained.

"I see. Do you mind if I join in on your lessons?"

"If Mama's okay with it."

"I'll ask beforehand."

"Ready to go to Mass?"

"Yes. What's the word for 'yes' again? I need a dictionary."

"Da. Are you getting used to the services now, Stasiya?"

I looked up "a little bit" and found it. "немного (nemnogo)."

"Very good! That dictionary that Mama and Papa gave you this morning is really working. I'm proud of you, Nastya, of how far you've come. May God keep and bless you."

"Spasibo." I said.

"Very good! пожалуйста (pozhaluysta) you're welcome."

"May He bless and keep you as well. I have a gift for you also, Mashka, and for the rest of you, for helping me with my Russian." I pulled out four silver necklaces with white beads on them.

"Wow, thank you very much, Stasiya! I love it!" Mashka squealed.

"And I also got gifts for your parents as well. Pardon me, Your Imperial Highnesses, Tsar Nikolai and Tsarina Aleksandra." I gave a curtsy.

"Yes?" Aleksandra turned around, her hair in an elegant bun, clothed with a white dress and earrings.

"I have a gift for you, Your Highness." I pulled out a book that I got from my mother. "It's from my mother, Your Highness. She left it for you."

"That is very sweet. Thank you very much."

"And, Your Imperial Highness?"

Nikolai turned around, his blue jacket with dozens of medals shining in the light. "Yes, Anastasia?"

"I have a gift for you. Here, Your Highness." I pulled out a cross that belonged to my father, before he died.

"Thank you very much. This really means a lot to me. It's time for Mass." The Tsar looked at his watch. "We're going to be late, Sunshine." The Tsar said to the Tsarina. "Get the girls and the tsarevitch and meet me in the chapel."

"Of course, Nicky." Aleksandra replied. "Children, it's time for the Christmas Mass!" She called.

The Imperial children walked elegantly, but rapidly.

"Yes, Mama, we're ready to go Mass." Olishka said promptly.

Tati is so proper. No wonder the children call her The Governess. I thought.

I escorted the Imperial Family to Mass, then attended it with them. I plan on becoming Russian Orthodox.

I'm so overwhelmed. I thought, as I stared at the priest, Father Grigory, giving the Mass.*

*Father Grigory did not give the Mass at that time. I made this part up.

Aleksei is well enough to stand, but he is still a little shaky, so one of the guards is with him.

After Mass, we had dinner, read the Nativity, and went to bed.
