Adult Birthday Party Invitation It is best to make it a point to include birthday request wording that adequately signifies the celebrant. Is the celebrant a humorous person? Or perhaps a serious person? Someone who loves poetry? Someone who likes sports activities? Your invitation should be tailor-made according to the celebrant's preferences. You don't need to consult the celebrant about how the invitation should be created, but your knowledge of the celebrant alone should be enough of the guide. If you are making invites for your own birthday, make sure the actual wording will reflect your own personality.
