I took a writing class in college where one of the assignments was to write an obituary for one of my grandparents. I procrastinated the assignment until the night before it was due because it seemed like a dumb assignment.
Scramming for an easy grandparent to write about, I gave my mom a call and asked her for some basic biographical information about my maternal grandfather, who was still alive.
As we were talking about his career, my mom couldn't recall the name of one of the companies he worked at. She lectured me about waiting until the last minute to write the assignment because it was late -- 10:30pm my grandpa's time. However, she said she would give him a call to see if he was still awake and be able to answer that question once my assignment was due the following morning.
When my mom called my grandpa, my grandma answered the phone in a panic. My grandma frantically explained that the paramedics had just arrived and was performing CPR on my grandpa because he had stopped breathing and passed out. My mom was able to stay on the phone with my grandma until they took my grandpa to the hospital, where he was declared dead.
In the time my mom and I had been talking on the phone about my grandpa's "obituary," he had died. We ended up using the obituary I wrote for that writing assignment as his actual obituary. Still freaks me out when I think about the timing.
