Most people who have siblings aren't close with them. I am lucky because my sister, who is three years younger than me, is my best friend. We grew up together, doing everything together, which brought us closer over the years. Now, I couldn't imagine my life without her, and don't know what I would do if I didn't have someone like her in my life.

1. She's known me longer than anyone else.

She knows everything about me. She's always the one I know I can talk to about anything because she knows me so well that she knows just what to say. Anytime I have a bad day, I know I can count on venting to her. Anytime I have something exciting to tell her, I know her reaction will be just the same as mine. She's just always been there so I know I can always count on her to know what to say when I need her.

2. She's my fashion police.

Whenever I go shopping, I always look to her for advice. It seems like she can tell when something looks ugly on me that I think looks great. When she's not with me, I'm always snapping her pictures because she always knows what looks the best.

3. She's always there when I need her.

Even if we were just in a fight five minutes ago, I can always count that she'll get over it to talk to me. Since we are so alike, we bicker easily, but once there is something serious that we need to talk about, our issues just disappear like the fight never happened, and we're back to normal. No fight has ever stopped us from talking. I know that no matter what, we can look past our differences and be there for one another.

4. She's the one person I talk to confide in about my family.

Every family has their fights. Whenever there is something I need to talk to her about my family, I know that she will understand because we go through some of the same things. She knows just what to say because sometimes she has already had the same fight.

5. She makes vacations and trips memorable.

I never worry about a family vacation being boring because I have my best friend there with me. Each trip is better than the last because I have my sister to hangout with. We experience new things together, and take a lot of pictures to capture the memories. I can't wait for this summer's trip because I know that we are going to have a blast.

My sister is my best friend, and nothing will ever change that. I hear from people everyday how jealous they are of our bond because some people will never have something this special with their own siblings.
