If you are a guest to be invited to someone's home, we should test some of this tiger. For example, the time has come to hosts who looked at what? Decent, if not to talk about things, just a social gathering early to be impolite. The hostess is doing to prepare, she has not completely ready you up, make her feel very embarrassed. As late as 10 minutes the best. As late as half an hour becomes too late, and need to apologize to the owner.
如果你被邀请到别人家做客,就要考虎这样几个情况.比如,该在什么时候到主人家?如果不是谈正经事,只是个社交聚会,早到是不礼貌的.女主人正在做准备,她还没完全准备好你就到了,会使她感到非常尴尬.晚到10分钟最佳.晚到半小时就显得太迟了,需要向主人致歉
