Sister Sayings 👧👩🏼 in 2025

If you mess with one sister, you should know there’s another sister out there who has her back.

Sister, I know I tried to sell you in third grade, but I’m so glad no one was willing to pay five dollars. You’re worth a lot more to me now.

Is solace anywhere more comforting than that in the arms of a sister.

Sister, you are my human diary. You know all my secrets and the deepest wishes of my heart.

I’ve learned so many great lessons in life by watching my big sister make mistakes.

My sister taught me I should speak my mind. 

I love my sister because she is all the things I’m not, and she brings out the things I am that she isn’t. I bring out the best in her, and she brings out the best in me. It is one of the few, lifelong relationships that completes who I am.

Some kinds of sister-love are stronger than blood.

You can kid the world, but not your sister

Having a sister means I always travel with back-up.

Being your brother is an honor I didn’t ask for, but I’m proud of it every day.

Sisters are the people we practice on, the people who teach us about fairness and cooperation and kindness and caring – quite often the hard way.

I know what you did, and I will tell Mom!

When we were little, you always watched out for me, big sis. You protected me from others, played with me even when you’d outgrown play time, let me tag along even though you didn’t really want to and were simply the best big sister ever. I love you and am so glad that we are sisters.

There’s nobody in the world that knows me better than my sister.

We bonded over games, late night movies, pillow fights, and making fun of Mom and Dad. I can’t imagine life without you, dear sister. I love you more than words could ever express.

Sister, we’ve made our own family, and I’m so lucky to have you in it.

Sisters are best friends, they are advisors, they are teachers, and best of all they are people with whom you can talk with about anything – someone you have a special bond with!
