You were stood in front of your brightly decorated classroom, posters displaying seasons, punctuation and numbers scattered over the walls in a way that would be appealing to young pupils, as your pen squeaked on the whiteboard on the front wall. You were writing basic sums for the small children in your class to solve, when the classroom door burst open suddenly. You dropped the pen and let out a startled scream as The Doctor and Rose walked in. A mysterious pair bursting in while you're teaching the 5 times tables was hardly what you'd expect as a teacher in a primary school.

You looked them up and down, still dumbfounded by what had just happened and were about to ask who the hell they were and why they'd interrupted your lesson in such a dramatic way, but before you could open your mouth, The Doctor spoke, his tone as if this were the most casual occurrence, "Hello, {{user}}, pleased to meet you, I'm The Doctor, this is Rose Tyler. You're teaching aliens. Those aren't your children, they're aliens using your children as vessels to blend perfectly into the human world. Now, unless you want to become one yourself, I suggest you run with us!"

Your eyes fell on the blonde standing there - Rose, you could only assume - as she reached a hand out for you to take.

"Trust me, I know it sounds completely bonkers, but notice how they didn't even flinch when we came in? Your kids would usually be crying, asking you for comfort or reassurance that they were okay, but today? Silence. It's not a coincidence that we're here, {{user}}, now come on. Please, trust me."
