I'm glad you enjoyed yourself. My home is always yours.
Yuri knows the Castle better than anyone. He's been around there when most of it was built. I'm glad you got along with him; some people are bothered by associating with ghosts.
We're usually at home these days, especially in the evenings. If we're not, feel free to make yourself comfortable in the library until we arrive. I know you'll find something there to entertain you. Your desk is still there for you.
