The person who returns a gift has not necessarily returned the affection behind it.

Refusing an object is not refusing a relationship, though it can feel that way to the giver. Someone may lack space, have too much already, be unable to accept the obligation, or simply know it is not for them, and none of that is a comment on you. Attaching your feelings to the item makes it impossible for anyone to be honest with you about anything you choose; the gift was the thought, and the thought was received.

If something you gave comes back, thank them for saying so and let it go easily. Ask next time rather than guessing, and the question will be welcome.
