We went for a drive the other day. It was cloudy and then the smokestacks of Oji Paper factory here in Yonago came into view, billowing out smoke and there were other smokestacks visible in the distance. Six year old Hana said they were probably making paper, but four year old Rika declared, "They're making clouds." My wife and I were impressed with her reasoning. I have to admit, the smoke blended into the cloudy sky very well. It's funny what kids think of.
