Back to that old routine

Well, after a scorching (!??!) summer break, it's back to the day job. These first few weeks are always the killers. If it's not the feeling of exhausting from going from a sedate speed in the summer to all-out-rushing in the space of a day, or the feeling of how different this class is (and the thought "will I ever get them to the standard of last years?"), then it's the battle against the first virus invasion that enters the school with the kids.
So far, I've suffered just from the first and second, but I can see children hacking in class and thinking it's only a matter of time before their bugs strike me down.
