It’s no wonder people mistake us for siblings rather than cousins because I too sometimes forget that you are my cousin as you’re so much more like a sister to me!
Happy birthday, my dear! I hope your special day is as special as you are to me!
If I had to give just one reason why you’re more like a sister to me than a cousin, it would be that growing up together you would annoy me just as much as any sister would!
I want you to know that I look up to you as if you were my elder sister, cousin. It has nothing to do with age, only the fact that you look so much older than me!
