Frequently Asked Questions
What should I write in a card for someone turning 30?
Acknowledging the milestone directly — rather than treating it like any other birthday — tends to feel more thoughtful, whether the tone is celebratory or lightly funny.
Is it risky to joke about turning 30?
It depends on the person — if they're openly anxious about it, lean celebratory instead; if they joke about it themselves, a lighthearted line usually lands well.
