Sometimes when he's thoughtful he gives me a creepy feeling.

At others, when he comes out with one of his easy, cool assurances that we are all right--that we will get each other--why, then something grim takes possession of me.

I believe him, I'm happy, but there crosses my mind a fleeting realization--not of what our friend is now, but what he has been.

And it disturbs me, chills me.
I don't understand it.

For, Collie, though I understand your feeling of what he is, I don't understand mine.
