I'm 17 years of age currently and I'll be 18 on the twenty-eighth of December this year. My mental age is currently unknown to me because nobody told me how young I act, I've been known to act very serious at moments but act like a child at others I express the ability to think deeply and logically but it depresses me so I try not to think about serious things, The foolish actions of most people my age confuses me it doesn't make them cool, They need to learn to act like themselves and to not try to impress others with these acts of foolishness.
My stock line to this question is: "I'm old enough to know better and young enough to not give a darn". Frankly, I'm old enough to be a father to most everyone that has replied here. I'm finding the maturity thing a bit amusing. We are all immature at times, whether on purpose or not it is just part of life. This is going to sound quite clichéd, but you really should try and stay young at heart and whatever you do make sure you take the time to enjoy life as you walk its path.
I hate to say it but there seems to be a section of society that will always think that is "cool". Hang tight and don't step down to their level. Any girl out there would ever asked me to participate in such antisocial behaviour would get my answer of "no", closely followed by, "there is a bus stop on the corner, find your own way home". Remember, 5 minutes of pleasure can lead to a life time of misery.
:derpe: Yeah, too many teens are idiots. Heck, too many adults are idiots. I feel like I'm going to have to pick up the world after them or something. The USA is not going to last much longer as a superpower with the people who are in charge in charge. Everyone is lazy, they want life handed to them. Am I getting off topic? I think I am. Anyways, yeah. Have I mentioned I'm tired? Cause I am. Very. Tired.
I'm 13. probably the youngest here, I started posting when I was 12. My maturity age can be whatever you want it to be, just wait 'till you hear one of my jokes that include sexual innuendo. Or I can be pretty mature. Seriously bro, I'm like programmable robot. With a sugar high. On cocaine.
