I have never had a sister of my own, and I sometimes wondered if I was actually missing out on something. I mean all my friends have ever complained about was having their closet picked through, and new stuff being borrowed without them even getting to wear it first. I considered myself kind of lucky for not having the same thing happen to me. I just didn't find it to be an opportunity missed.

How can you actually miss something you've never had? That's how I looked at it when it came to my lack of sisters. I was content with having a baby brother, and though things weren't always great, we ultimately ended up being pretty close.

Until one day, things just decide to change in your favor.

My best friend, my boyfriend, my lover, and my go-to-guy, showed me his best friend, partner in crime, and sister. After getting to know you, I realized that all these years of not having a sister could finally be made up just by being lucky enough to call your brother my boyfriend.

You see, first meeting you, I was intimidated. I heard so much about you, and how important you were to him. If I didn't make a good impression, I knew my relationship with my boyfriend would suffer, and truthfully I could understand why. When you love someone, you want them to love the people you grew up with. That's completely understandable, so I knew how important it was right off the bat.

Had my brother not liked my boyfriend, I'm not sure how strong of a relationship would have actually continued. You see like you, my brother is my best friend, so I kept reminding myself of just how crucial getting you to like me was.

Your brother and I went over everything together..what to talk about, what not to, subjects to avoid, and subjects that were a hit or miss. I had everything memorized I wanted to ask you, and I was determined to somehow get you to like me.

I'd start out saying I heard so much about you, then proceed to ask you about your dogs, maybe follow it up with a question about school and what you were into..

I never realized just how easy meeting you actually was until the night was over. I don't think I asked one thing I told myself I would because conversation easily flowed from that moment and continued over these past few years.

In this little time, I have gained a best friend out of dating the love of my life, not just with him, but with you as well. I now see why you're so special to him, and I admire him and you both for maintaining such a strong relationship.

I guess what I'm trying to tell you, is thank you. Thank you for being something to him that at times I can't be. Thanks for understanding things that maybe occasionally, I just can't get. And thank you for loving him with everything in you and protecting him at every possible moment.

The special part about seeing my boyfriend love his family so much, is I start to imagine the way he'll love his own family one day. You were able to give me a glimpse into the future, and the thought of it excites me every single time.

Not every brother-sister duo has a special relationship, and truthfully, a lot of the guys in my past relationships didn't have what the two of you do. I came into this relationship with him not knowing what to expect, and I think that's the best part of it all. Without expecting any of this, I have gained two best friends-practically the same person but different genders. I have learned to let the hard things slip from my mind and focus on the things that make me strive to be better. Both of you are partly responsible for this.

I'm almost shocked with myself that I didn't anticipate this more before I met you. That just like him, I'd love you too. All of your goofy outbursts, your love to help every animal you can, and the determination you have to succeed. You're such similar people, and I can't help but feel blessed I get a two in one deal.

To my boyfriend's sister,

Thanks for being my sister too.
