He had been here so long, with all these awful frumps, brooding over one idea, never getting away from this Religion.
Martin began to imagine himself very cleverly leading his father into a normal natural life, taking him to see things, making him laugh; it would do his health a world of good.
Then, quite suddenly, the old man said: "And what do you remember, Martin, of the old days here, the days when you were quite small, when we lived in Mason Street ?" What did Martin remember?
He remembered a good deal.

He was surprised when he began to think ...

"Did he remember ..." his father suggested a scene, a day--yes, he remembered that.
