Tips for Writing a Personal Message
Sometimes you want to add your own twist to a wish. Writing something personal makes the card much more meaningful.
Start by thinking about your relationship. Is it funny, serious, or strictly polite? Match your tone to that reality. Mention a specific memory you share, like a fun vacation or a holiday disaster you both survived. This proves you value your shared history.
Compliment her specific traits. Instead of just saying “you’re nice,” mention how she is a great mom, a patient listener, or the best cook in the family. Finally, sign off with a warm closing that feels natural to you.
