Which excerpt helps refine the idea that Bertha gets joy from little moments?

A.
"[The baby] ate delightfully, holding up her lips for spoon and then waving her hands. Sometimes she wouldn't let the spoon go; and sometimes, just as Bertha had filled it, she waved it away to the four winds. When the soup was finished Bertha turned round to the fire." (paragraphs 31–32)
B.
"Some yellow pears, smooth as silk, some white grapes covered with a silver bloom and a big cluster of purple ones. These last she had bought to tone in with the new dining-room carpet. Yes, that did sound rather far-fetched and absurd, but it was really why she had bought them. She had thought in the shop: 'I must have some purple ones to bring the carpet up to the table.'" (paragraph 14)
C.
"'We went to the park and I sat down on a chair and took her out of the pram and a big dog came along and put its head on my knee and she clutched its ear, tugged it. Oh, you should have seen her.' Bertha wanted to ask if it wasn't rather dangerous to let her clutch at a strange dog's ear. But she did not dare to." (paragraphs 20–21)
D.
"Mary brought in the fruit on a tray and with it a glass bowl, and a blue dish, very lovely, with a strange sheen on it as though it had been dipped in milk." (paragraph 11)
