[ WP ] It 's 300 years in the future , and you 're a history teacher . Today 's lesson is on the early 21st century .

Mr. Wilson let our a long drawn-out sigh, solemnly accepting that it was time for class. He dropped some coffee pills into his cup of water and watched as it turned to coffee. Well `` Coffee''. That's something that has n't changed since the beginning of the 21st century, the coffee that's served at school is still absolutely horrid. Like thickened sewage only less appealing. `` Time to go'' he snapped his fingers and his holo-glasses sprung into action, correcting his poor visage as well as showing what class he was supposed to teach. `` Ah, it's'that' class''. As he approached the classroom the nearest wall vanished into thin air and Mr. Wilson sat down at the desk in front of the class. `` Seems like we're missing some students'' he remarked. His favorite activity of the day was about to come around, locking out late students. A young female student came running towards the classroom. `` I'm sorry!'' she cried out. `` Please!''. Mr. Wilson nodded in her direction and waited until she was a few feet away from the entrance before snapping his fingers. A window formed at the place where the entrance was just moments ago and Mr. Wilson waved goodbye to the student that was beating on the glass from the other side. The rest of the class felt visible sorry for her, which in turn brought old man Wilson great enjoyment. `` Well then, let's get to it.'' he piped. `` Whiteboard, 21st century''. The entire wall behind Mr. Wilson's desk started to distort, revealing images of 21st century tech. Simultaneously Mr. Wilson's face distorted into a frown. `` Who wrote on the wall again? In permanent marker!''. Mark, a young man with blonde hair - one of the many students in class, said `` Probably the math teacher Miss. Goodwill.'' `` That senile old fart'' he growled. `` Eh, Mark. Where did we finish last time?''. `` I believe we talked about forms of communication during the 21st century'' Mark replied. `` Ah, yes. That means we have now arrived the popular form of self-expression trough imagery where one would place himself on the edges or center of the picture, it was dubbed'Selfie'''. `` We will spend the remainder of class talking about a particular kind of'Selfie' that was quite popular during the 21st century.'Duckface'.'' Mark twitched in his seat.
