Suzy Sunshine
Someone, especially a female, who is frequently or excessively happy and optimistic, perhaps naïvely so. You have always been a Suzy Sunshine, even as a kid. No matter what happened, you always had a smile on your face and saw the best in things. I know you think I'm some little Suzy Sunshine all the time, but this stuff weighs on me, too.
