There is nothing modest about the Leo. They are very proud and self-confident. You can find the royal label on everything they do or say. They will not even start a project unless they think they will come out on top when it's finished. They are generous, affectionate, charismatic, and often theatrical in their behavior. If you hurt their pride they will argue with you until you give them something they can walk away with that boosts their ego. They are generous often to a fault.
Sounds like someone I know ...
Happy Birthday
