Dear Michael, There are moments in life that define who we become, and watching you grow into the man you are today has been my greatest privilege. From those early morning walks when you were barely old enough to tie your shoes, to the graduation ceremony where I watched you cross the stage, every memory is etched permanently in my heart. I want you to know how proud I am—not because of the achievements, which are many, but because of the person behind them. The kindness you show to strangers, the patience you have with those who struggle, and the courage you demonstrate when facing difficulty are the qualities that matter most in this life. Your mother and I often talked about what kind of man you would become. We hoped. We prayed. And you exceeded every hope we ever dared to hold. There were hard years, years where nothing seemed to go right, where the path forward disappeared into fog. You walked through those years without losing your compass. I have kept every letter you ever wrote me. They are in the wooden box on the shelf in my study—the one with the brass clasp that sticks in winter. When I miss you most, I open that box and read them. The handwriting changes over the years, from the large careful letters of a child to the confident script of a grown man, but the voice is always yours. There is something I never told you, because I was afraid the words would come out wrong. The proudest moment of my life was not the day you won the award, or the day you got the promotion, or even the day you married. The proudest moment was a Tuesday afternoon when you were eleven years old. You found an injured bird in the backyard and you sat beside it for three hours in the rain until it either recovered or passed peacefully. You did not want it to be alone. That is who you are. Remember that. With all my love, now and always, Dad

What to look for when reviewing the email
Flag ON is WORKING if:
• Writer and Preview line density looks similar to the PDF
• Text fills roughly the same vertical space on screen as in PDF
• Page break intuition matches (you'd expect 3 pages)
Flag ON is WRONG if:
• Writer/Preview text appears much more cramped than delivered PDF
• Significant visible gap between where text ends on screen vs PDF
• You would expect the letter to fit in fewer pages based on Writer view
After visual review, report back with your observation. Decision: Turn OFF (rollback) · Keep ON (accept) · Further validation needed.
