Love my sister more than I'll ever admit to her.

Sisters are the best therapy.

Sis, you're my favourite.

Big sis knows best.

Sisters make the best memories.

My sister will always be my best friend.

Adventure is better with my sister.

Sister squad.

Happy birthday to the best sister ever.

Sister bond: unbreakable.

My sister is my hype girl.

She's my other half.

Sisters by blood, friends by heart.

Me and my sister against the world.

Sister, my first adventure buddy.

Two peas in a pod.
