How to personalize a friendship card for best friend
These cards are best when they're for no reason. Reference a recent moment together, or a quality you appreciate about them. "Thinking of you" is a complete card if it's true. Friends rarely expect a card and almost always remember getting one.
When you're writing to best friend in particular, lean on shared history — a memory you can name, a habit you've watched them keep, a moment you'd both remember. The relationship deserves a sentence the rest of the world couldn't write.
What to avoid
Don't use a friendship card to settle a score, raise a grievance, or fish for an apology. Don't get heavier than the relationship can hold — a card is not a place to confess long-buried feelings if doing so would change the friendship.
