Black-Eyed Susans

When I was a kind in school there was a girl I liked and she liked me. We talked would talk all the time and once I led the conversation to find out her favorite flower. I thought I could use this knowledge later to make her happy. Except the only time I ever used it was to make myself cry because I didn't talk to her much after that and a few years later she died of cancer.
I was going to put a bouquet on her tombstone, but I didn't want to have to explain myself to anyone so instead I just imagined that I did. I suppose that since she is dead now the thought counts more than the action, and now whenever I see Black-Eyed Susans I cry.
