Happy birthday to my true soul sister, my dear gal pal for life.
The fact that you came into this world from another mother is the one and only thing that sets us apart from biological siblings, and you’ll always be able to quote me on that.
A lifetime of gal pals couldn’t compare to the wonderful friend that you are! You are more like a sister to me, just from another mother! Happy birthday!
Happy birthday to you, my dearest sister from another!
I am so thankful to your mother and father for giving me the greatest gift in the world: you! You are a one-of-a-kind friend and one I am so lucky to have in my life.
