One of the most important phases of growing up occurs during early puberty when one makes the painful discovery that ones parents are not as perfect and invincible as once imagined.

The natural reaction to this is to revolt by becoming even more independent in an exaggerated way, resulting in increased irascibility, fits of anger, and being against everything for the sake of proving some imagined point.

For parents this is a most difficult period, but realizing that this is a natural path to becoming oneself and surviving better in the big bad world, makes it just a little bit easier to deal with.

Ironically, once they grow up and become adults going off to live on their own, that is when they become closer again and feel an urge to come back more often than not.
