A gift is only a gift if it’s a joy to receive. It’s not an imposition about relevance.
A gift that inspires you may be a bad choice for the recipient. (I once received a gift certificate for an upscale steakhouse and got the phone promptly slammed on when I called to inquire about vegan dining options.) Or the recipient may think you’re using gifts to buy their affection or assert your preferences.
It’s understandable to feel disappointed when your gift isn’t used as you intended. Try to get over it. You gave the gift out of choice, and now you have no control over how the recipient uses the gift.
Getting your gift misused doesn’t mean they’re rejecting you. It just means that you have dissimilar tastes and preferences—a trait that most relationships should weather.
If you perceive you’ve hurt the recipient’s feelings, apologize and retract the gift in favor of something more appealing to the recipient.
