Your Grandfather, postmortem I may clarify, was carefully gutted and stuffed with all the necessary taxadermological materials you could find in the forest. Essentially, you taxidermized your Grandfather after he died. Luckily, he had taught you how to do so prior to his death because, as it turns out, your family used to be one of taxidermists. More specifically, your grandfather, his father, and his father before him, all became expert taxidermists, as well as surgeons and scientists. In fact, your great grandfather was the original discoverer of black holes. He noticed that when was studying a special star in the sky was viewed from earth at exactly 4:13 AM on April 13th of the year, the star would be covered by a black hole. And you could see the star in two places at once.
Of course, this discovery took a while to prove as it needed perfect positioning, and the positioning was only once per year. But after several years of confirmed observation, the black hole between earth and the star was confirmed to be true.
The rest of your family have similar discoveries, such as cognitive dissonance, time dilation, and other nonsense like that.
You never knew what discovery your own parents made, perhaps it was something special. You spend the next few minutes thinking about all the cool things they could've done.
