Look here, Roger, you can't keep this up!

ROGER

No, I can't keep this up. Besides, it's going to rain to-morrow.

MARGARET

What do you mean?

ROGER

Watering the plants. Isn't that what you meant?

MARGARET

You aren't watering the plants. I've been watching you for half an hour.
If you only would! But you keep forgetting what you are at.

ROGER

I wish it were only forgetting--it's remembering.

MARGARET

Oh Roger, don't I know? But you mustn't!

ROGER
