Interesting how scientific findings over time change our reality of the world isn't it? I still often forget that Pluto is now a moon instead of a planet. But it was always a planet when I was a kid! Now I have to see it as a moon?
That would be a funny way to break up with someone. "At first I saw you as promising, now I just see you as an idiot." Okay, so not everyone has my sense of humor. ;)
So if I'm ever a grandparent, given that I lived in the desert most of my life I probably won't be able to get it past my grandkids that I had to walk 10 miles uphill everday in the snow to get to school. But I COULD say, "When I was your age, Pluto was a planet!"
