'Oh non, je ne regrète rien..' the song says.
It's much like that, but still are there some missing parts about that sentence.
Missing parts about life. This is just a moment in which I see what I'm missing now. I see the things of which I know I ought to have had them right here. With me, or at least in my heart. However, I don't regret the most important happening in my life, and I'm glad about that. I mean, there are worse things in this life. It's easy to say 'shit happens', cuz sometimes it really does. Then dreams are better than reality, even when they are nightmares. I would prefer a dream over reality right now, so I could be where I ought to be, I could go where I belong.
Life isn't always fair. Actually, it is more often unfair than fair. And what can we, what can I do but accept it? No one can change it. Life can be a party, but the decorations are up to yourself. I wish I were more sensible right now. I wish I knew what to do.
