The rules are simple, you ban the previous for any gratuitous or witty reason. Humor is mandatory, teasing recommended and flirting highly appreciated. Do it with courtesy and an amicable spirit.
Dear children, as pupils of this venerable and so envied institution, I expect of you that you abide by all the rules which all of you should know by now. I recommend you the utmost respect for your teachers, the staff, your elders and colleagues. I will leave you for the daily business in the care of our general governess Ms. Ren, but you can always find me in my office for any question or problem you face. Obey her and be gentle to each other and serious in pursuing your banning training and studies. I wish you now a merry and successful year.
