I think that I have quite a lot in common with first years. I have recently started in a new school. Having taught in a lot of schools and been around a lot of staff rooms, I have learned a thing or two: "You can't sit there! That's Mr. Kelly's chair!" or "I know you're new around here but I've always parked my car in front of the shed. Don't worry - you can move it at lunchtime" or "I'm sorry but you're going to have to finish your tea quickly, as you're drinking it from my cup". Here's my advice: bring your own cup; park in the spot furthest from the school; be the last man (or woman as the case may be) standing at lunch time!
So relax first years! You're not alone!
Luckily our class has made it through the first term relatively unscathed. I think incoming first years would benefit from their words of wisdom. First years: post at will!
