Be PoliteThe Big Word here is courtesy. Courtesy is a unique commodity; priceless to receive yet it costs nothing to give. The simple rule is, be polite to everybody.2. R - E - S - P - E - C - T, find out what it means to me.Respecting someones opinion is more than just acknowledging their right to have one. Usually someone elses opinion is just as valid as yours, whether you want to admit it or not. If you want people to take your opinions seriously, take theirs seriously.Respecting other peoples privacy is at least as important in an SCA Group as it is in the real world. While some of us dont mind sharing the details of their personal lives with the group, some of us are more private. Respect that. This doesnt mean that you cant or shouldnt ask personal questions, but if someone doesnt want to answer or doesnt want to go into detail, leave it there.Personal respect is a bit tricky, as it tends to mean different things to different people.

They may be wrong, they may even be right, but they probably dont have a dark ulterior motive.My last word on respect is this: Consider every person worthy of your respect, until and unless they prove by word or deed to be otherwise (and even then, thats no excuse for rude behavior on your part).3. Open Hailing FrequenciesThe key to solving any interpersonal problems that may arise is communication. If you dont like something someone has said or done, tell them so politely. And when at all possible tell them privately. Symptoms of HIV/ AIDS 艾滋症状HIV is transmitted by bodily fluids, such as blood, semen, breast milk, and vaginal secretions.
