Friendship birthdays are the ones where the words matter most. There is no obligation holding it together — you chose each other — so a card that says nothing more than "have a great day" undersells the whole thing. Below are 140 birthday messages for a friend, sorted by tone and by the kind of friendship you have. Take one as it is, or splice two together. When you have the wording, our Birthday Flowers can be delivered the same day with a hand-written Greetings Card.
