Dear [Name of colleague],
It makes me happy to wish you and your spouse a lovely 25th marriage anniversary. On this special occasion, I wish to express that, this is the day to celebrate the bliss of today, reminiscences of yesterday and hopes of tomorrow. There is no more lovely, friendly and charming union than marriage and you both have defined the feeling in a perfect manner. On this special day, your dreams have grown big and yielded you both the results of your togetherness.
Love at first sight is easy to understand but two people looking into each other’s eyes for lifetime is a miracle indeed and this day reminds you both the miracles for lifetime. This day reminds you the essence of your happy married life and the foundation of your unending love. As you both will grow old together, your physique will change, situations would change but the thing that remains unchanged will be your incessant love for each other. I wish, someday I can find the kind of love you experience today. Your bond would grow stronger day by day and this day depicts that feeling. Attitude is the difference between a tribulation and a voyage and you always have the right attitude and approach towards life which makes your married life a successful one.
Like you hold my hand in every professional juncture of life, may your partner continue to hold your hand in your personal junctures for years to come. Lots of happy wishes on this special day.
