Remember, gifting is a shared experience, meant to be appreciated by the giftee as well as the gifter. It’s obvious that your partner put thought into the gift, and that should be appreciated. Giving thoughtful gifts is not an easy task. Just because you have a new item does not diminish the value of the old sentimental one. But demanding the new one be returned could easily sow resentment in your relationship that will be revisited every gifting season.
