What do you learn in secondary school??And what was your biggest mistake??

Many things are latent by experience;and mostly you  get this thing when you learn from your mistakes;No one is prefect. One can make false perfection but no one is prefect in this world;and who is perfect is not human being. In my high school i learnt from my mistakesOnce in class argument i called my brother from his class that this girl is fighting with me;he came ;he said politely to that girl Rabia (now my  best friend) you are sisters;don't fight with each other so try to compensate with each other. But she started to cry that Fatima brought her brother to beat me. Principal got news about it,He rebuked both of us;but i felt sorry for my brother  he was not on mistake:due to my mistake he was insulted
