Once, when I was really, really tired and didn't want to go to school (this was probably the 3rd or 4th grade), I pretended to remain asleep while my father attempted to wake me up. I guess I though that, well, maybe he's give up if he tried hard enough.
However, when he started shaking me harshly and pretty much screaming, I decided to have it his way. So I opened my eyes, and with a sing-song voice that was reminiscent of a stopping elevator, shouted, "Dinggg!"
My dad immediately grabbed me, pulled me into a suffocation hug, and started crying.
I felt so bad about it that I never did anything like that again.
