This made me laugh to read this because I always think of writing something positive in my poetry which I am not known for, and sometimes the thoughts do come or I get an idea, but then more often than not, it ends up exactly as your last lines there and it is like something over takes the pen and the darkness creeps though the ink ????
The metaphor here ahh! This is the definition to me of a bittersweet poem, and the brevity worked well to illustrate that as well. The hope and rebirth promised in spring, at perhaps the start and onset of a relationship, and then the complexities of them, where it makes it more difficult to write and remember them. It made me think of several things: people passing us in our life who we thought were permanent fixtures in our world, who we became loyal to, yet they were not committed. And how memory can be something we want to hold close to, but at times, want to completely fade away and not set in stone, in ink.
