24. Sitting here wishing you a happy 12th birthday, but also admiring your beautiful smile as I listen to my favorite song. Thinking back over the last twelve years, and all the memories we have shared together. From elementary school where I had you in my class, to middle school and junior high where we became inseparable best friends, and then the senior year we attended different schools. We made sure one of us would go to the other’s games, parties and parent notice night.
25. Happy 12th birthday. Thinking of you on your birthday and wishing you many wonderful things. I hope it is a special day in every way possible. I love you my little sister!
