When Are People Going To Realize That Age Is A Number And Nothing Too Big?

Because a person can be mature, but not legally an adult making some unable to provide for themselves. For instance a 14 year old gets pregnant, she isn't legally able to work where I live so how is she to provide for the child? Parents are great support yes, but not even mine could afford to help my sister enough when she had her first and still till this day she doesn't have a GED or diploma and she has a very hard time finding jobs. She is in her late twenties now and she has willingly said "I chose to act as an adult thinking I was ready, but I wasn't"... And even though she loves all of her kids she wishes she had chosen to wait. So what I am saying is that we tell those younger than us that it is wrong and that they are to young because we have seen the consequences and would rather not see someone else go through the same thing. Not because we don't think you are mature we just care about your well being.

I am not saying stop them from having sex any kid is gonna figure a way to do something behind their parent's back I am saying be educated about your decisions first and use protection. Most of all don't always count on someone to be there to help either. I don't know where you live, but where I do there are child labor laws and you have to be 16 to work and only with parent or legal gardean's concent.

I know what you mean. I'm 20 and been married for 8 months now. When I tell ppl this they automatically assume I got pregnant. I did not get pregnant I just happened to fall in love with my husband. I knew it was right cause I felt different with him then my other bf's. Older ppl say to me "well your marriage isn't going to last long at all." You know what I tell them? I tell them that 75% of the adults who get married , their marriages will last average 2 years. That just comes to show your not too young. Also just because a lot of kids are immature doesn't mean ALL are. I was always told I acted too mature for my age and I am. Now I'm saying a lot kids think they are ready when they are 13 14 or 15 and they are usually not. But/ also their is mature kids out there anyway so good for them. What does it matter? When you go to bars or anything 20-27 year olds aren't very mature themselves. HECK, when I'm at work I get middle aged women who are very immature...so in conclusion you make your own decisions and if they are bad you learn from them.

People much older than 14,15,16, are not ready to make good decisions, you're right it doesn't mean you are too young to have feeling and that your feeling are not just as important as anyone. But history has shown and most people agree as you have more growth as in age you naturally have more experience and wisdom in order to make better decisions. It doesn't mean your feelings are not valid it means they could be temporary and will change as you mature. So be sure before you label them permanent that you understand there's nothing wrong with not declaring things permanent.

Tell you what if a 14,15,16,17 year old is done with high planning college  has a job lives on there own and has had experience in life not guy's and friends life then yes they are very mature on the other hand if you call being mature knowing just about guy's and what they should do you might have a lil growing to do

Because this is usually the case unfortunately. If more people acted mature at that age I would agree wholeheartedly with you but I am afraid they do not for the most part. Case in point children having children. I see a lot of the teenagers getting pregnant and the young father leaving because he was not ready to have a child yet. I agree you are not going to stop them from having sex but I think it best to at least warn them of the consequences and explain the necessity of birth control. We have way too many people in this world already.
