…pull this exact expression when reading a particularly shocking scene in a book? 

Just read a scene that was all shades of horrifying and I was sat there, hand clapped over my mouth, whispering “Oh my god, no, no, no…” much to the confusion of my family.

What I like is when I see this reaction in random people reading on the subway or bus. I sit there, scrutinizing them while simultaneously suppressing the urge to demand all the details of said shocking scene. Somehow, I think seizing a stranger by the shoulders and shaking plot twists and drama out of them is frowned upon… 

What’s the most shocking/unexpected thing to ever happen in your fictional adventures?
