"Age ain't nothing but a number"

I hear this saying Alot. "Age ain't nothing but a number"
Yeah don't you hear it alot. But everybody has their own opinion and I feel that its not how long you been here but how much you know? Some people are very mature for their age. Like if you know alot Book wise,street wise then you should be able to get a job and do mature thing's. I'm not saying be fast grown but challenge ur self. And some things people mess up on. Is that they think when you have sex ur mature. Being mature is being bigger than people so be mature not stupid.
