What to write in a 40th birthday card

1. Lead with the joke if they joke first. Forty is the most self-deprecated birthday there is; follow their lead.
2. Say the confident thing. “You know who you are now” is the compliment forty-year-olds actually want.
3. Name what they built. Two decades of adult life is worth acknowledging specifically.
4. Avoid decline humor. Knees and bedtimes are funny; anything implying they are past it is not.
