Don't listen to these trolls it's easy let me walk you through it, You go to the secret room in the tower and you will find the postmasters mom. After you slap the living daylights out of her face you get an achievement titled "Bad Ass Kid" - inside joke... you get the blue lighting around your head and an exotic engram.
