How can we not like Amelie? She wants the best for everyone around her. Thus she tries to change the lives of many of those she meets, not at all without a certain manipulation, but the intention is always that they should get better - that they simply deserve better lives.
She herself grew up with a father who never hugged her, and where his monthly medical checks of her was the only form of touch she experienced. Therefore her heart beat extra hard, something her father misinterpreted as a heart defect, and thought it was best she did not start the school. Her neurotic mother was to take care of the teaching. But after a visit to Notre Lady is hit by her mother by a falling Canadian suicide tourist, and makes Amelie's father widower. And yet we have only just come to the forewords.
