When I was a kid, we lived in a city three hours away from my grandparents. They rarely visited, since my grandpa was suffering from an illness, and if they did visit, I typically knew in advance.
One day, I was looking out of the window and saw my grandpa waving at me from the driveway. I told my mom, super excited that they’d planned a surprise visit. My mom didn’t say anything. Years went by and I forgot about this, but she retold me that story recently…and apparently, my grandpa had just died that morning.
