Their child did not violate causality as much as he challenged his parents sense of order. Finishing dinner preparation does not cause people to eat it.
An invasion of people who are stateless and come to work jobs that nobody wants is not an invasion. If you have eaten a vegetable, a fruit, a piece of chicken or pork, if you live in a house with walls, YOU have benefited from the labour of undocumented workers and have contributed to an irregualar job economy.
This reminds me of Augusto Monterroso’s “The Dinosaur”.
