The baby sister

Is it always fair to say the baby sister is the spoiled one? My baby sister is turning 29 today and in my case, it's safe to assume this girl is a brat. It was always my mission to protect her, from when she was very little, through her teenage years, through stomach aches and heartaches, to her wedding day and still to this very day, I can only say it's an instinct of mine. I'm most proud of her, she speaks her mind, she doesn't take crap from no one, and she'll always and fiercely have your back. I couldn't ask for a better sister, well, the 3 others are not so bad either....but it's always the baby....
