Agreed. And at the point of their lives when they are out of college starting their careers is when you see the characters grow and mature the most. That is why i love to look back at the highschool seasons compared to the adult years because it is sometimes crazy how much they have grown as people. They have taken that time to find themselves and find where they are in the world. I am 21, and even though i am still in college, like you said, it is realistic because at this age you start to find your career path and everything.
I agree, if OTH didn't have the 4 year jump then it would have ended pretty quickly, but even though people might say that adult years werent as good as high school years. Can you imagine if they showed the college years? That would have been worse!
