Neither dared look at grandmother.

Both grew very red.

At last, "I am _so_ sorry, grandmother dear." "I am _so_ sorry, dear grandmother." "We are both _so_ sorry; we _quite_ forgot we were to write them this morning." Grandmother looked at them both with a somewhat curious expression.
"You both forgot ?" she said.

"Have you so much to do, my dear little girls, that you haven't room in your minds to remember even this one thing ?" "No, grandmother, it isn't that.

I should have remembered," said Sylvia in a low voice.
"I don't know, grandmother dear," replied Molly, briskly.
