Why a pierce... for what?

Out on the street, on to the first corner you go and see a girl with a pierce in her right part of the mouth, it was big and it made her look ugly. Very strange even if it looks ugly she doesn't even care about it.... passing by her,I asked" do you like what you got?" but she answers" are you stupid!",seems she doesn't know her image, she looks awful ... she runs of afterwords... I still can't figure out what we gain by doing this piercing ?, some say that's how we hide our hate, some say that's how we punish from our sins.It's not helpful this to stop what happens between some of us, I think socialization it's one of the keys we need.
I got colleges that you could ask " hey, why you got pierce?", the answer comes like this " it's fashionable".... well if they say it's fashionable to be an irrational animal, seems we all go down one by one ... we are changing our gens man becomes women and viceversa...
We are living on a disintegrated planet,on our own bomb, destructing us without even knowing why we do it and how... at least I;'d tell myself where to but a pierce to don't show ugly because of some motive,I don't wanna look like a pig ... I'm afraid of what we are starting to create we are like nanobots who destroy almost everything in their way...
I'd recommend you to find a day, to look in the mirror, and at least once try be yourself don't hide behind this things... and be careful who you name as a friend and who to follow, because is it possible to see your wrong, but just when it's to late, don't forget no one can judge you for what you are....
