What does Mrs. Dalloway remember of Peter Walsh?

Mrs. Dalloway remembers Peter's sayings, his knife, his smile, and his grumpiness.

He would be back from India one of these days, June or July, she forgot which, for his letters were awfully dull; it was his sayings one remembered; his eyes, his pocket knife, his smile, his grumpiness and, when millions of things had utterly vanished – how strange it was! – a few sayings like this about cabbages.
