I was sitting at my kitchen counter munching on leftover pizza when my phone pinged with a text. A dear friend was offering condolences on the death of another friend. My pizza dropped from my hand, and my breath caught in my chest. I had been away recently, distracted for a few weeks with travel plans, exhausted after returning home. Just the day before I thought about emailing my friend but didn’t get around to it. Now, she’s gone.
