You know when your teacher asked you whether you’d done your homework and you told her an elf magically hid it under an invisibility cloak? Yes, my lovelies, that is lying. Although us writers prefer to call it experimentation.
You lie through your teeth and watch the reaction. In this case, for example, the teacher probably did not ask what colour clothes the elf was wearing. I doubt she asked if you if it fly away and left it’s cloak behind or took it with him. You probably got whacked! Oh! Corporal punishment is illegal, but I’m sure your ear was hurting.
The thing is, it doesn’t work in school, but after you turn twenty-six and forget your lunch it’s the funniest joke in you new social circle. Much more fun than discussing who the new office witch is!
