A sister is a friend for life.

Having a sister means always having a plus one.

The best part of my childhood? My sister.

Sisters make everything better.

Big sister, bigger heart.

Happy Sister's Day to my forever friend.

My sister wins every argument. Rudely.

Sister love is the best love.

Sisters: the family you get to keep forever.

Sister bond: unbreakable.

She's my forever travel buddy.

My sister, my secret keeper.

Sisters share everything. Except the last cookie.

We grew up together and we're still growing.

Sister squad.

The best gift my parents gave me: my sister.
