So your sister has been watching Doctor Who all day.
Me:
Yeah I know! I got her hooked! Have you been watching it with her?
Dad:
No, I fell asleep. But I know he goes around the universe in a blue telephone box thing... and there were these robot things that attacked... and aliens everywhere....
14-year-old sister, from background, watching Doctor Who:
DAD. THEY'RE NOT ALIENS. THEY'RE JUST DIFFERENT. THEY'RE JUST DIFFERENT CREATURES FROM DIFFERENT WORLDS.
