Dear Dad, On your special day, I want to wish you a very happy birthday. You have played so many roles in my life, from teacher to mentor to friend. You have always been there for me, offering support and guidance whenever I needed it. Your wisdom, kindness, and strength inspire me every day, and I feel blessed to have you in my life. I hope that today, and every day, is filled with love, laughter, and joyful moments. Thank you for everything you have done for me and for being the best dad I could ask for. I wish you a very happy birthday and a year filled with love and happiness. Love, [Your Name]
