There is a song that I will always associate with my mother: "Can't You See" by the Marshall Tucker Band. My mom listens to southern rock and, for some reason, I feel like this song is the quintessence of the genre. It used to bring a smile to my face.
During a depressive episode some years ago though, all I could think about when I heard the song was that she was getting older and that she would soon die. The sorrow was inexplicable and came upon me suddenly one ordinary afternoon. I cried for no reason at all. My mind was in such a bad place then that I couldn't see the good in anything, only the bad, and so it is with this song.
