i know plenty of adults that are know it alls and act younger then teens, i dont think dissing teenagers is very fair
I don't think anyone has, as you put it, dissed the teenager, rather, tried to understand and offer understanding but from your responce that may be at your time in life beyond you.
As for being know it alls. Simple math with clear that up for you and you may become enlightened.
16 years of living, The first 12 tied to an apron string = 4 years of life experience.
Know it all, 65 years of living. The first 12 years tied to an apron string = 53 years of life experience.
Now do you really think you can compete with that life experience which you attribute the term of, Know It All.
A very wise person once said. A wise person learns from someone elses mistakes, a fool learns from their own. Worth thinking about, don't you think.

As always I take ownership of my spelling mistakes
