Deciding what to write in a birthday card depends on how well you know the recipient. Write a message you feel comfortable sending to the individual. Taking just a few moments to write a personal message shows the birthday card comes from the heart. Remember to wish the recipient a happy birthday and sign your name at the bottom of the card. Mail the card about a week in advance of the recipient's birthday so it will arrive on time.
Consider a funny message for friends or family with a sense of humour. Mention the person's age if it's a milestone birthday, like 40 or 50. Think of humorous memories or incidents from the past to reference. Using someones increasing age for a joke will garner laughs. Consider ideas like, "The nation's best kept secret: Your true age." or "So many candles...so little cake." Remember your funny message should not be hurtful or mean, but lighthearted and silly.
Write an inspirational message on a birthday card. Use an inspirational message for co-workers or people you consider acquaintances. These messages are ideal for people you don't know as well because they are not offensive or hurtful. Consider an inspirational message like, "May this day bring you all the things that make you smile. Happy Birthday" or "Today is your day to shine. Happy Birthday." Try adding a compliment to the message such as, "I hope that your birthday is as wonderful as you are."
Including a message of love is ideal for a significant other, close relative or friend. These messages should be reserved for those people closest to you. Writing a love message for a significant other is different from one you would write to your best friends. Consider these message for a significant other. "It's as easy to stay in love with you as it was to fall in love" or "To the world you are one person, but to me you are the world." Expressing your feelings to a friend indicates a different type of love. Try a few of these messages for friends. "It's always a treat to wish a happy birthday to someone so sweet" or "I'm so glad I can share this special day with my best friend."
