One of the most ludicrous things parents say is “Why aren’t you more grateful to us for feeding, clothing, and sheltering you?!”
It’s because you’re the parent. You have a duty to feed, clothe, and shelter your children. You’re not doing them a favor by making sure they don’t starve. You’re fulfilling one of the responsibilities of parenting. Your children don’t owe you for doing what you’re obligated to do.
