I really like the way #3 is phrased. The book Facts and Fancies from 1930 is full of do's and dont's. There are lots of warnings, especially. Warnings about deadly automobiles and leaving farm gates open and the sorrow that is forgetting your mouth harp at home when you go to summer camp.
There is silence now, and I dread the thought of time's passage and the squirrel's close proximity to the radiator.
