I'm going to tell a child she will never find Dory.
Is this meant to be a reference to the kid's movie?
Yeah. Finding Dory is one of her favorites and I'm going to tell her that since she can't breathe underwater she will never find Dory.
It is mean to hurt children's feelings. She obviously really loves the movie, so telling her that is just cruel. You should be nice to children.
You're talking about a kid who can't even read yet.
Just because she can't read doesn't mean she doesn't have an imagination. Kids love thinking about and playing pretend. Bringing the harsh realities of the world on her at a young age is just mean.
