I wanted to get something extraordinary and particularly special for a cousin who is more like a sister to me, but then I realized something: You already have all of that in me!
I hope your birthday is as wonderful and as meaningful as you are to me, my dear! Wishing a very happy birthday to you!
You are a wonderful cousin and a great friend. You are a rock I can hold on to whenever I’m in trouble. Thank you for putting up with me and for always being by my side.
Have a great and wonderful birthday as you deserve!
