Gratuitous advice refers to advice that is given without being asked for and often feels unnecessary or unwarranted. The term "gratuitous" suggests that the advice lacks justification or a clear reason for being offered, indicating that it may be more intrusive or presumptuous than helpful. Therefore, describing gratuitous advice as forthcoming and unwarranted captures the essence of its unsolicited nature and the common perception that such advice is not necessarily needed or appropriate in the given context. This aligns with the understanding that while someone may intend to be helpful, gratuitous advice can often come across as overstepping boundaries, thus making it seem unnecessary.
