Happy birthday to my favorite gal pal! We might come from different parents, but two friends like us will always be so much more like sisters than anything else!
Today is your special day so I won’t make it all about me, but as you turn another year older I can’t help but be reminded of the fact that I’m even older than that! Thanks a lot!
Birthday gifts are overrated I think, sis, so starting from now I think we should just exchange sweet birthday wishes instead! Happy birthday, my dear!
