My parent keeps asking me for things I do not want to give. Does honoring them mean always saying yes?

“Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.”

This line arrives at the very beginning of Scripture, long before any commandment about parents, and it says a person leaves father and mother to form a new household. It is describing a design rather than a rebellion. God's own account of family assumes that a real separation happens, and that an adult child is meant to become the head of something instead of a permanent extension of their parents' home.

“And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?”

Luke tells the only story we have of Jesus between infancy and adulthood, and in it he does something his parents find genuinely upsetting. He stays behind, and when they find him he gently declines their framing of what happened. Two verses later Luke notes that he went home and was subject to them. Both things sit in the same paragraph: a clear no about the thing itself, and no dishonor.
