When I was little my family went to Bodie CA, a ghost town. At one point we went into a little museum and in this museum was an area with larger items, such as a hearse and a little kids pull toy that has a string on it.
Well I would go over and just stare at this toy, my dad would bring me over by him and I'd go right back to this toy. He finally asked why I kept going over there and I said the girl is playing with her toy.
We eventually went to leave and our last stop was the cemetery. My mom was taking me around and was reading headstones and was going on about infant mortality rates and how this headstone says this person died at two weeks old because she's weird. Now as a three year old who couldn't read yet this was all going over my head without impact.
I get to one headstone and I just lost it, I'm crying and it's not I'm hungry tears it's someone died I'm heartbroken crying.
My parents are asking what's wrong and I start saying "I'm never going to see her again she's gone." They ask who's gone and I reply "The girl that was playing with her toy."
We get back to where we were staying and my mom bought a video about the town and watched it with my grandfather and at the beginning they show the headstone and I just started saying I'm never going to see her again.
Come to find out I had started crying at the headstone of a gir about my age who was acidentally killed by her dad because she walked up behind him and he caught her with the backswing of a pickaxe. She died right around 100 years before I was born, I was born in June and she died in August I think.
