After a few weeks, why does Kit start to look forward to Willim's Saturday visits?

From the text:

There was water to draw and linen to scrub and, everlastingly. the endless rows of vegetables to weed and hoe. Kit had not found a single one of these tasks to her liking. Her hands were unskillful not so much from inability as from the rebellion that stiffened her fingers. She was Katherine Tyler. She had not been reared to do the work of slaves. And William Ashby was the only person in Wethersfield who did not expect her to be useful, who demanded nothing, and offered his steady admiration as proof that she was still of some worth. No wonder that she found herself looking forward to Saturday evening.
