I have found things in my house that I never bought or brought into my house. One day I walked out of my bedroom and there was a pair of earrings laying on the floor just outside my bedroom door. I very, very rarely wear earrings. I look stupid in them; and I never bought those, and even if I did buy them a long time ago and just forgot, why were they, all of a sudden, laying on the floor? If I did buy them, I haven't ever worn them, so why were they laying on the floor?
