Frequently Asked Questions
What is a meaningful thing to write in a birthday card?
Specificity beats generic wishes. Referencing a shared memory, an inside joke, or something you genuinely admire about the person transforms a card from forgettable to meaningful. Instead of ‘Hope you have a great day,’ try something like ‘Still laughing about that disaster dinner we cooked together. Let’s make more terrible decisions this year.‘
What do you write in a birthday card for someone you don’t know well?
Keep it warm and brief. A genuine wish like ‘Hope your birthday is as great as you are’ works better than straining for intimacy you don’t have. Avoid forced familiarity and stick to simple, sincere sentiments.
