Hi Kristina, this is such a nice touching story! I enjoyed reading it and watching the beautiful pictures.
It reminded me of my relationship with my favorite great-uncle, who also passed away around the same time your grandfather passed the bridge. I wrote a poem about his last departure. Since I was a child, my great-uncle always playfully called me his tiny spaceship in orbit flying far to explore around for him; and he would always know where I was because he would keep in touch with me via radio ... In your case, your grandfather is the satellite and you keep the radio in sync on him! :)
Thank you for sharing these special memories, Kristina.
