Weird, bizarre, strange, unusual, which one is it?

About 8 years ago I took a kitten I found at my work to my close female relative (okay, my sister). She decided to keep the cat. I went over to her house 3 weeks ago. While I was there, I asked her about her cat (whose very shy). For that reason it rarely comes out when anyone else is in the house but my sister. So I went looking for the cat. I was crawling around on my hands and knee's at times searching, all the while my sister just watched. I never found the cat and it never revealed itself. Last weekend I visited her again. I can't remember if I said anything about the cat, but then my sister blurts out, "do you know what I've been going threw"? Then tells me the cat is dead. And that she had it euthanized just over a month ago if I remember right. Regardless, that means the cat was dead long before I went looking for it. She watched me search for maybe 15 minutes crawling around looking for a dead cat, that I brought to her. What do you make of this?
