"Nice girls dont get the corner office"

As we get older we grow out of many things like calling people names and other non-sense that occurs on the everyday elementary playground. But what kind of non-sense goes on -on the adult playground? I certainly don’t need to name a few of the obvious things that people do to each other ie:guys/girls and relationship games that are absolutely ridiculous.
But do we grow out of being mean? Sometimes I feel like im on the grade 5 playground full of competition, confrontation and blindsided hits. Being mean is to do something to purposely hurt someone or annoy someone. I thought we'd grown out of this -but its a jungle gym out there and the mean kids can still come out to play. The modern jungle gym is different though, survival of the fittest has allowed us to become professional grade 5 bullies. Tactics are no longer treated by saying "sticks and stones may break my bones but names will never hurt me" because there is no rhyme for the world of jealousy, manipulation, competition, and narcissism that we play within. Unfortunently were all capable of this and its almost necessary every once in a while when the stakes are high
