The two things that made me cry most as a child were 1: the fate of "Ju-ju" and 2: the Oscar Wilde story "The Happy Prince". In both cases I had to go to the bathroom so no-one would see the tears!
For "Seven Little Australians" it was the marvelous TV production that turned on the waterworks,, but I read the book too.
A colleague of mine had a narrow escape when a big branch fell on their family picnic. It's a thing!
