Woo, I know some people that have maturity issues. I hear them say, "Jesus, stop that, grow up and act more mature."
Well, well, well, --yes father dear!
But you see, there is where the problem is--" act more mature". Holy fahzoli, because It takes more than wearing adult clothes, ("get a haircut and get a real job"), and not participating in "juvenile" activities, like dancing, or listening to that darn rap music. I know you know that some of the most mature people are the most stupid. I know you have to sit through classes with a few preps. They dress more mature, and do lots of homework and go to cheerleading or football practice, but really a great deal of preps are just as bigoted, prejudiced, potty mouthed as any of us losers.
What I'm trying to say here is that you need to think mature to be mature. You need to think and act to be mature. If thinking and acting aren't completely assimilated you immaturity will shine through either in the way you think or talk to people or in the way you act.
Example #1: If you think that jewish people are "fucking gay" you might call people "fucking jews" to insult them. I know perfectly "mature" people have a tendency to do this. I know you have a right to say and think what you want but I think that it can be agreed upon by virtually anyone that making prejudgements about people and things that you don't know is pretty damn immature and pretty damn stupid.
The bottom line is if you are extremely intent on being mature you really need to think about what the fuck you are doing, and how it can be seen from other people's eyes.
