Frequently asked questions
What should I write in a 12th Birthday Boy Wishes card?
A milestone card should name the milestone explicitly — the year, the round number, the threshold being crossed — then say something about what those years actually contained, not just that they happened. The 64 examples above pair the marker with a real observation; borrow one and add the detail that makes it specifically about them.
How specific should I be about the milestone year?
Specific. A '50th anniversary' card that doesn't mention fifty years feels like a generic anniversary card with a wrong number on the envelope. Reference the years actually lived — what they built, what they survived, what's still ahead — and the card stops being a milestone box-tick and becomes a record.
Can I personalise these 12th Birthday Boy Wishes with the recipient's name?
Yes — and personalising by year is the easy win. Drop the round-number marker into a line that previously just said 'this anniversary' or 'this birthday', and the card immediately reads as written-for-them rather than picked-up-from-a-rack.
