Dear... B
This isn't your fault, even though I still feel like it might be. You may not ever know what I mean by this, but I don't want to blame you for what happened, it's not something I like to do, blaming people, but I always seem to work out a way to justify it. This is me, writing to you as a neutral party before I find fault with you.
Before we break apart, though we haven't even met, I wanted you to know all the things I'll try to tell you later, except later you won't listen. Don't blame people, because there's always a reason behind everything, no matter how crazy or insignificant it is. People do stupid things by accident sometimes, because nobody is perfect. Remember that everyone believes in something, and everyone strives for something. Don't spend too long fixing broken people, or you'll end up broken yourself. You can never do enough for the world, so my advice is don't start what you can't finish. Random acts of kindness are enough. For every good action, there will be a negative consequence, focus on the good ones. And perhaps the most important thing I can tell you, is that yes, life isn't fair, nor will it ever be, so even if you can't find all that much good, make some more through yourself. Write sets of rules and stick to them. No matter what. Don't betray yourself for somebody else. Because if you have to then they aren't worth it.
I'm sorry if this looks more like a list of potentially terrible advice. Because in essence, that's all it is. But it's the truth, and these are my rules. You don't have to follow them, but do create your own. You can be your own person, you can be freer to choose your side if you listen to not just the right people, but all people. And if they don't have a side worth joining create your own. Please. If you can hear me listen. This is my first truth to you, and will be my last. Don't take it for granted, any more than you would take your parents for granted. They must have been good at one point in their lives. Maybe you can prove that.
