Irony. And by the way, no one <20 is mature.
Small note. You could be talking about mental maturity or physical maturity. Physical maturity, you'd usually be right with that statement. Mental maturity varies on both how you define mature and who you talk to. There are many adults who do not meet my standard of maturity, for instance.
Alot of people lie about their age on that
I don't lie about my age. I'm really -1 years old.
Trying to act otherwise is a waste of your youth, enjoy it while you have it.
Of course.
And a small thing to note is that while age might be the most common thing to base maturity level off of, it's not always perfectly accurate. I'm done posting here today, and just got back from pouring some concrete in a posthole at the house in New Orleans, so I'm gonna go take a shower, and head back for my college dorm later. See you folks later. Woosh.
