Theory about a mysterious gift last Christmas

Just before Christmas, I received a book from an anonymous person. I saw the Amazon Prime sticker on the box and thought that it was something that I had ordered that had arrived. I ripped the box open and still don't know who sent me this book.

I have been thinking that it may have been the ex-guy. He has an Amazon Prime membership. He obviously knows where I live. I haven't communicated with him since I told him to stop contacting me last July. He has never mentioned anything about this book. He likely got confirmation that the shipment was delivered and was satisfied with that information.

The book? It's The Longevity Paradox by Steven R. Gundry. It's essentially a book about how to live a long, healthy, happy life.

Perhaps the ex felt guilty that he broke my heart and ruined a part of my life that this book would help me. Maybe he truly wants me to live a longer, happier life.

Anyway, I haven't read much from it. I suppose that I should and see if I do grow old, happy, and healthy.
