From what I have read, explaining gifts can come up in a lot of therapy. While not all gifts are a problem, and small homemade baked goods are common and not often a big deal - they can be.

" Many if not most authors seem to agree that a gift in psychotherapy requires the therapist to express genuine appreciation and gratitude and, when appropriate, to also explore the meaning and conscious or unconscious intent of the gift with the client (Knox, et. al. 2003)"
