"I didn't raise Todd to be a writer, but he happened to be one anyway"

Anne McCaffrey's quote talks to the idea that sometimes our children will take courses that we did not expect or plan for them. It recommends that while we might have specific expectations for our children, they might select to pursue something different. This quote likewise speaks with the idea that our kids are their own people, which we ought to not be shocked when they make decisions that are various from what we had prepared for them. It is a suggestion that we should be open to our children's options and support them in whatever course they select. Ultimately, it is a tip that our kids are people with their own dreams and goals, and that we must be open to whatever they select to pursue.
