My sister's laugh is contagious.

Sister selfie!

Sisters: built-in best friends.

Double trouble.

Big sister, bigger heart.

Sisters: forever connected.

Sister, confidante, co-conspirator.

We might not always agree, but we always have each other.

Stuck with her for life, and happy about it.

My sister, my sunshine.

Thank goodness for sisters.

Two sisters, one shared brain cell.

Little sister, big personality.

Happy birthday to the best sister ever.

My sister is my biggest cheerleader.

Life's better with a sister.
