Recent wet and cool Obon season taught Mei-Shun that summer is going, autumn is coming. For example, she was really happy to hang futon mats outdoors after waiting as long as 10 days. However, no warmth was left when she brings them in around 17 : 00 — they kept heat within even at dusk a month before. Sunset is getting sooner, sunrise later. More and more sunlight is creeping into rooms.
