Cover art for Cherry Blossoms lyrics by Horrible Crowes, The

Just some speculation:

He has been upset about his love leaving him (possibly for someone else) and has been dealing with it by going out to the bars, getting drunk, and then going for a drive to clear his head. This particular time he drifts into thoughts about her and begins to wonder what she would do if he were to drive off a bridge and kill himself. He's obviously bitter in thinking that she would just continue on with her life with a new man and think nothing of it. In the end, however, he drunkenly crashes his car into a cherry tree. He seems to just be injured as a result.

This may also be about someone close to him dying (maybe a child) instead of his love leaving him for someone else. Cherry blossoms tend to be a symbol for mortality for how beautiful they are and how quickly they die.

Or maybe it's a combination of both. I don't know.

That is horrible!!!! I cannot even bear the thought!!!!
