Tips for writing your own 25th birthday captions

• Add one detail from your day. "Chapter 25, starting with pancakes at Dad's" says more about you than the number alone.
• Use your own sense of humor. Pair a quarter-century joke with a thank-you if that sounds like you. Funny and grateful can share a caption.
• Make a friend's caption personal. Name a shared memory or the birthday plan: "Happy 25th to my favorite road trip navigator. Same playlist tonight?"
