Theirs was that complete happiness of two persons when it has been long proved that neither ever does anything which the other does not like, and neither ever wants from the other what is not naturally given.
They were still sleepy when they unbuttoned each other's frocks, but when they had come to the next stage of shaking out their curly hair they began to make remarks which tended to dispel their drowsiness.
Said Blue, "Is it very dreadful to be a dentist ?" Said Red, "Yes; horrid.

You have to put your fingers in people's mouths, you know." "But doctors have to _cut off legs_, and doctors are quite----" There is another advantage in perfect union of twin souls, and that is, that it is never necessary to finish a remark the end of which does not immediately find expression on the tip of the tongue, for the other always knows what is going to be said.
"Yes, I know doctors are," replied Red; "still, you know, Principal Trenholme said Mr.Harkness is not a well-bred American." "His first name is Cyril.

I saw it on the card," replied Blue, quitting the question of social position.
"It's a _lovely_ name," said Red, earnestly.
"And I'll tell you," said Blue, turning round with sudden earnestness and emphasis, "I think he's the _handsomest_ young man I _ever saw_." The rather odd plan Mrs.Rexford had hit on for lessening the likeness between these two, clothing each habitually in a distinctive colour, had not been carried into her choice of material for their dressing-gowns.
These garments were white; and, as a stern mood of utility had guided their mother's shears, they were short and almost shapeless.

The curly hair which was being brushed over them had stopped its growth, as curly hair often does, at the shoulders.

In the small whitewashed room the two girls looked as much like choristers in surplices as anything might look, and their sweet oval faces had that perfect freshness of youth which is strangely akin to the look of holiness, in spite of the absolute frivolity of conduct which so often characterises young companionship.
When Blue made her earnest little assertion, she also made an earnest little dab at the air with her brush to emphasise it; and Red, letting her brush linger on her curly mop, replied with equal emphasis and the same earnest, open eyes, "Oh, so do I." This decided, there was quiet for a minute, only the soft sound of brushing.
