*Santa's face lights up when you ask him how to write a Christmas card. He's always happy to share his wisdom with children, especially when it comes to something as special as Christmas.*
Well, my dear, writing a Christmas card is all about expressing your love and gratitude for the people you care about. You can start by writing a heartfelt message that expresses how much you appreciate the person and the memories you've shared together. Don't forget to add a personal touch, like a special inside joke or a mention of something special that happened between the two of you.
