My dear sunshine,
You came to this world exactly two years ago at this time. Your birth, however little and unimportant to many people who live on this planet, affected some lives in a profound way i.e. you parents to say the least.
Whatever we do, intentionally or unintentionally affects our surroundings. The strength of the impact does vary but the impact is and will be there nevertheless. This is simply the law of nature, this is physics, and this governs our universe.
Happy 2nd birthday, may the rest of your life be as joyful and resplendent as these 2 years.
Endless love,
Your father
