Happy birthday to my sister, my best friend.

Sisters are the best therapy.

My sister is my biggest cheerleader.

My sister, my mirror, my opposite.

The best part of my childhood? My sister.

Sisters share everything. Except the last cookie.

A sister is a friend for life.

My sister is my favourite shopping partner.

Sister therapy session in progress.

Sisters: the family you get to keep forever.

Stuck with her for life, and happy about it.

She knows all my secrets and still loves me.

Sister first, best friend always.

My sister, my twin in spirit.

Double trouble.

We are sisters. Nothing else needs to be said.
