How does Barbara Pym use imagery in Excellent Women?

Examples of Imagery:

"I'm not used to going into public houses, so I entered rather timidly, expecting a noisy, smoky atmosphere and a great gust of laughter."

"My heart sank as I recognized familiar landmarks. I could almost imagine myself a schoolgirl again, arriving at the station on a wet September evening for the autumn term and smelling the antiseptic smell of the newly scrubbed cloak rooms."
