Here are some ideas for what to write on a birthday card, depending on the tone you want: 1. Friendly and casual:
- "Wishing you a fantastic birthday filled with fun and laughter!"
- "Hope your day is as awesome as you are. Happy Birthday!"
2. Heartfelt and sincere:
- "May your birthday be filled with love, joy, and all the things that make you happiest."
- "Wishing you a year ahead full of blessings and wonderful moments. Happy Birthday!"
3. Funny and light-hearted:
- "Age is just a number—unless you're a cheese! Have a great birthday!"
- "Another year older, but definitely not wiser. Happy Birthday!"
4. For family:
- "To my amazing [brother/sister/mom/dad], happy birthday! So grateful to have you in my life."
- "Wishing you health, happiness, and all the love in the world on your birthday!"
If you want, I can help craft a specific message for a particular person or style.
