For most club members there is a sort of natural conflict of priorities that arise from a conflict of circumstance.
Specifically, club members traditionally have the primary goal of having fun.
Mr. Sanford is, however, functionally still at work while this is happening.
There are many things someone might say or do during a board game, a card game, or even a semi-friendly round of Smash Bros. that are just not appropriate at Mr. Sanford's place of work.
So in order to help you all understand the boundaries surrounding your behaviors, we must first understand Mr. Sanford's situation.
Mr. Sanford is at work, running a club. He has put in paperwork to make sure that the heating and cooling continue for his room. He has been made aware that district administrators have a right to pop in and observe his club meeting if they want to. He is also aware that he is not always the only organized meeting going on in the school, and not even always the only one going on in his hallway. Mr. Sanford could be doing other things with his evenings and nights, I assure you, so he is giving up time. Also, the food. While I realize the amount of food that each club member receives might feel small, Mr. Sanford spends, week after week, a sizable amount of money on providing food and drink during these meetings (not to mention the minutes he loses every week to explaining the boundary between club food and his personal food).
In return, Mr. Sanford asks that you avoid certain things that are to be avoided on school grounds anyways:
1) No bullying or harassment.
2) No assault neither battery even when it is consensual (such as whipping one another with lanyards).
3) No inappropriate language, especially being yelled loudly.
4) No PDAs.
5) No vandalism.
6) No theft.
7) No being out and wandering for any significant amount of time (because of the liability this creates for me).
If you are the sort of person who absolutely needs to do at least one of these to have fun, this is perhaps not the right club for you.
