Subject: Sofa area mess, again.
Body:
Dear all,
I know how hard it is to lift our hand and hold our garbage and walk a few steps to the garbage can. However, there is a rule that prohibits food or drinks outside of the cafeteria and it has been announced a few times using class times. This rule has not been very well enforced and the people breaking the rules are supposedly in higher grades. Nonetheless, we all have the responsibility and a great heart and I hope we can all try our best and overcome our greatest difficulties of not living the life of a bum.

Subject: Sofa area mess!
Body: This morning I saw the mess in the sofa area and it is ridiculous! You are high school students! You should learn to clean up after yourself. This is ridiculous! This is not the market, the trash cans are just down the hallway and you are so lazy to go there? Don't give me any excuses, anytime I see another student leave garbage behind he will be punished. One more time I see mess in the sofa area, whoever leaves trash behind will get a detention and the second time will be suspension!

Subject: Please clean up after yourself.

Dear Students and Faculties of PAS,
I'm sure you all have noticed about the indecency in the sofa area. Regarding this issue, students must clean up after themselves or the rule of no food will be imposed more strictly on students who does not comply. This mess has been a great issue throughout the year and I hope we can create a better and cleaner learning environment for everyone. Let's work harder in keeping our community clean. Thank you.
Sincerely.
