<p>I was just contemplating this. One girl I know says this about herself. She is fairly mature, but every time she says it I lose some respect for her. From her, I find it immature and annoying, like she’s trying to elevate herself above the rest of the kids at school. There are a few times I’ve heard it and agree and it just comes up in conversation.</p>

I was unfamiliar with the word mature when I was a little eight year old :p</p>
