If you are part of the group, which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it will be appropriate for you to make a passing remark about the inedible canteen food or the chairman’s notorious bad taste in ties. With other audiences you mustn’t attempt to cut in with humor as they will resent an outsider making disparaging remarks about their canteen or their chairman.
