And Father never mentioned it at all.

Not a word.
But he's been queer.

He's been awfully queer.

Some days he's been just as he was when I first came this time--real talky and folksy, and as if he liked to be with us.

Then for whole days at a time he'd be more as he used to--stern, and stirring his coffee when there isn't any coffee there; and staying all the evening and half the night out in his observatory.
Some days he's talked a lot with me--asked me questions just as he used to, all about what I did in Boston, and Mother, and the people that came there to see her, and everything.
