There's this great movie based on this concept!! I wish I could remember what it was called, it was foreign, swedish I think. There's a happy couple, two kids on a ski vacation to the alps? Anyway they're having breakfast at an outdoor cafe on the balcony. An avalanche starts at the mountain nearest them and it's exactly like the entire balcony is going to be hit hard. The couple immediately reacts on pure instinct. The man just runs. Like doesn't look back, doesn't grab at least one kid and warn his wife, doesn't yell a warning nothing. Just fucking runs. The woman immediately without thinking picks up BOTH kids and runs while frantically looking for her husband in the chaos, she spots him and start trying to catch up.This guy doesn't look back once. It soon becomes apparent that the balcony wasn't within reach of the avalanche after all. The avalanche settles, no one is hurt, even those down below. Looked way worse than it was.

Such good acting, the family is standing together trying to process everything and that man's sheepish horrified face when he realizes what the fuck he did is amazing. She is just as horrified, glaring at him, shocked.

The rest of the movie follows the couple's marriage unraveling while he tries to cope with the self hate and guilt and she comes to terms with her new knowledge of her husband. Some friends join them, they have a debate about whether he's culpable because it wasn't a conscious decision, his body reacted but of course, her unconscious instinct was the children and him, and his wasn't. The movie explores the impact of the event on the people individually and as a couple, as well as the impact on the children. One of them was old enough to grasp the significance of his father's actions.

Great movie. Holy shit I would never be able to look at him the same way ever again. The marriage would be over that instant.
