The best card messages are short and specific. One true detail is better than three grand adjectives, and the person reading will know the difference.
For a birthday
- Another year of you being the first person I call. Happy birthday.
- I hope this year is as kind to you as you are to everyone else.
For an anniversary
- Still the best decision I ever made.
- Eleven years, one kitchen, no regrets.
To say thank you
- You did not have to, and you did anyway. Thank you.
- I would not have got through this month without you.
To offer condolences
Keep it simple. There is no need to explain or to find the right words, because they do not exist. Naming the person you are remembering is often the most comforting thing you can do.
- We are thinking of you and your family.
- Remembering [name] with so much love.
