Following on from the stupid things thread, did you tell your younger siblings lies?
I told my brother he was adopted but it was a secret so he couldn't mention it. It was a year before he asked my parents if it was true.?
I also told him that things dropped on the floor became poisonous. I gained a lot of chocolate and some rather nice felt tip pens that way.?
After learning the definition of 'pervert' as 'someone who watches too much television' (playground discussion) I reported this to my brother... Who then announced my Dad was a pervert during Christmas dinner a week later.
