I came to the realization today, driving on the highway on the way back from bringing the kids to school, that my understanding of grief has been too shallow. The catalyst was nothing more significant than a song on the radio. It was a song about loss in familial relationships, and it triggered a domino effect of realizations that suddenly and unexpectedly overtook me. I felt my face involuntarily transform into a contorted mask, as tears began to flow. I found myself trying to blink my vision clear enough not to crash as I navigated traffic on my way home.
