My sister rarely, if ever, reads my work so I'm going to go on a limb and talk to her boyfriend without actually talking to her boyfriend. You know who you are and I hope when you read this, maybe you will understand me more, and I, you.

My sister is pretty much my best friend and I am hers (or at least I hope I am). There is this book series we both read a few years ago called 'The Mortal Instruments' and there is the word, 'Parabatai', and it is a special bond between two people that links them till death. It's also a symbol in the books, a sort of tattoo the two people get and with it, they are one, and if one died, the other would lose part of themselves. Me and my sister immediately looked at one another and said, "We're parabatai right?"

We had it planned that once we turned 18, me before her, and when we had the money, we were going to get the parabatai symbol tattooed on us. We are going to be each other's maids of honor and we even talked about being surrogates for one another if one of us couldn't have children. You see? We are one. She is mine and I am hers. So maybe you can see where I am coming from when you showed up and started to take some of her away from me.

I definitely do not mean this in a mean way and I also won't lie to you and say I'm not jealous, because I totally am sometimes. What I am trying to say from this is that we can share. It sounds horrible, us sharing a person without actually telling the person what is going on - that person being my sister, who is also your girlfriend. Most of the days, for now, she is with me, but her attention is always elsewhere, which is you. And when she is with you, sometimes she is texting me.

You should probably know that I most likely know certain things about you. Some is bad, not horribly bad, but most is good. I learned a lot about you, like what you like to eat and your family. I learned of the dates you guys go on and sometimes what you talk about with my sister. I'm not saying this to show that I am the knower of all things about you but I say this to show that I know how much my sister likes, well loves, you. And know that sometimes it is hard for me to hear that and know that my parabatai is living in a completely different world that doesn't involve me 24/7 - more like 5/2.

You should also know that with this all said, I am happy for her.

I am happy for you.

You get to have a life with someone who I think is one of the best people in the world, obviously other than my other siblings who are too young to date, and that you get to live in a world with her 24/7.

Do know, she is still my parabatai, a bond you will never have (again, not to be mean) but it is something that she and I are on the same level, where your relationship with her is a level I will never be on nor understand. I will continue to know things about you and it will only continue to have me like you even more for my sister until she gives me a reason not to anymore, which I hope doesn't happen anytime soon because at this point you are family.

Thank you for sharing and thank you for making her happy.
