Group Social Situations
Sometimes, it is possible to have conversations which reflect well on yourself when you are speaking with only one other person. When other people start joining into a group, however, it is easy to inadvertently start dominating a conversation and thus cause others to become annoyed and possibly even think of you as arrogant (this happens to me sometimes). If you have a friend, or even a good acquaintance who is aware of your social difficulties, ask him or her to give you some sort of signal when you start acting in a way that others will think of as obnoxious during group conversations.
