Dear Gauri,
Wishing you a very Happy Birthday! I hope your day is filled with smiles, laughter, and all the happiness you truly deserve. Even though I am far away this year, my thoughts are with you every moment today.
You have always been more than just a sister to me. You are my guide, my strength, and someone I look up to in every phase of life. I still remember how you helped me during my exams and stood by me during difficult times. Your care and love mean everything to me.
I truly wish I could be there to celebrate with you, cut the cake together, and share those special moments. But distance cannot reduce the love I have for you. May this year bring you success, good health, and endless joy.
Take care and enjoy your day to the fullest.
With lots of love,
