There's nothing I could ever say that would be equivalent to how much you mean to me and how thankful I am for you.
You are 13 years younger than me and I look up to you every day.
You make me want to be the best me I can be.
You motivate me every day to try hard for everything.
You remind me every day that I am your role model and that you are looking up to me. I know I don't have much longer before I move out and I cherish all the cuddles and kisses you give me.
You are always welcome to come sleep with me in my bed and stay up late watching 5 minute craft videos with me. I love making you laugh and laugh because you're laughing vice versa. I would do anything in the world to be able to take you to college with me. You're the cutest and funniest little girl I have ever met.
As you get older, I am always going to be here for you. You can come to me for anything. I will never judge you or make you feel bad for venting to me about things. I always want to spend time with you. I love coming home from work and seeing you as soon as I walk in the door and start playing with you.
I'm so thankful I have you in my life and you are the only thing in life promised to me. You will always be my sister. You will always be my "built in" best friend. You may be a lot younger than me, and I know you can't even read this yet, but I can't imagine my life without you in it. You've had such a positive impact on me and I want to be just as much of a positive influence for you.
Thank you for being the best little sister anyone could ever ask for.
