Cheery Happy Birthday Card. Everyone knows someone who's an optimist. They don't sweat the small stuff and they always look on the bright side of life. They have a great sense of humor and they don't want some stodgy birthday card. No gray-scale and stuffy font for them, please. Give them bold, bright rainbow lettering and hey, put it on a star background, if you can. That's why you give them this birthday card, because like them, its glass is always half-full.
