3. Hand-Written Note
As great as generic birthday cards are, it means so much more with a personal note. Scribble inside the card some warm wishes, maybe a memory or two. You don’t need to write a novel but a simple note of gratitude that your friend is in your life. I like saving my birthday cards for this very reason. And they’re great to pull out after a few years and reread, so it’s a win-win!
