Give me a free summary of the short story "The Japanese Quince."

Beauty and alienation are underlying themes that can be
found beneath the surface of John Galsworthy's short story, "The Japanese Quince." The
story is seemingly a simple one: One spring morning as he peers out his window, Mr.
Nilson notices an unusual "sensation" in his throat. He decides to investigate the
wonderful smell coming from the nearby gardens. While there, he finds that a neighbor,
Mr. Tandram, is also admiring the tree from which the smell emanates. Though they are
next-door neighbors, they have never met; and though they seemingly are quite similar in
appearance and in their love of what they learn is a Japanese quince, they feel uneasy
being together. After a brief conversation, they both return to their homes separately.
As he begins to read his newspaper inside his home, Nilson is "unaccountably
upset."
