Writing Trend of Rubbish Materials on Walls

 Have anyone of u seen the walls of our country,city,or even schools?  Houses or any public places having written strange words on it looks so strange .I live in Pakistan and as a Pakistani i strongly condemn this type of activities .Whenever I read this type of stuff on the walls of any place ,i think what image of our Country we are presenting to the world? .People usually use pens,chalks,even metal nails to write even scratch our walls and write their names,poetry,abuses,any political statement or any improper stuff which is very bad thing .This is such a big disaster activity but we ignore it and dont notice it .We all should consider it and need to take proper steps to stop this disaster activity.
