bread beside drink

I was about a thousand miles from home, sitting in a coffee shop in Kansas City. I was missing my wife and children badly. I was just having coffee and what was probably the greatest blueberry muffin i have ever. I was studying for my calculus 2 final to help pass the time. I thought it was strange to be that lonely, and still enjoy that muffin so much. I guess that’s what is meant by “bittersweet”
