Dear Anna,

I'm sorry for ignoring you today. It was extremely difficult for me.

I am no longer used to having people other than father and mother around me, and the way you nearly bowled me over as soon as you saw me was a little overwhelming – I was scared I might just freeze everything then and there.

Father and mother noticed what was going on and sent me to the library to study – I hope they weren't too hard on you.

I was so happy to see you again, despite everything… I'm sorry I couldn't let you know how much.

I've started studying all kinds of things, like languages, math and the history of the Kingdom. Math are fun – I find that they're a nice distraction and a good way to concentrate. Maybe they can help me stop using my powers by counting backwards when I'm nervous or worried.

I'll let you know if it works.

Your sister

Elsa.
