I began to notice other things then, too.

Their fathers and mothers didn't live in rooms at opposite ends of the house.

Their fathers and mothers seemed to like each other, and to talk together, and to have little jokes and laughs together, and twinkle with their eyes.

That is, most of them did.
And if one wanted to go to walk, or to a party, or to play some game, the other didn't always look tired and bored, and say, "Oh, very well, if you like." And then both not do it, whatever it was.

That is, I never saw the other girls' fathers and mothers do that way; and I've seen quite a lot of them, too, for I've been at the other girls' houses a lot for a long time.
