Alice is looking after her father, but that doesn’t mean she’s pleasant to him. He gets some distasteful looks as the food is served.
He seems grateful nevertheless.
They eat together at the table. They say little. When they’re done, however, Kev begins to open up to Alice. He repeatedly tells her about his worries, particularly about their lack of money.
