No.1 Eating with your mouth open
第一条：吃饭时张嘴咀嚼
Eating like an animal is simply one of the worst social mistakes you can make. It graduates from merely a bad habit that reflects poorly on you to something that actively disgusts other nearby people trying to enjoy their food. Women in particular find this awful, and it's one of the most common stereotypes of a hopeless, classless guy. This applies to more than just eating for that matter: The term "mouth-breather" is not exactly synonymous with refinement and social graces, so take your cues from that and ditch this habit as soon as humanly possible.
狼吞虎咽是最大的社交禁忌。它可能只是你身上一个小小的毛病，但却有可能极大地影响到周围人的食欲和心情，尤其是女人。难看的吃相不仅仅影响别人吃饭，还会让人觉得你是个没有前途、地位低下的家伙，而这个问题则严重得多。“用嘴喘气者（美国俚语：笨蛋）”可不是优雅、有风度的同义词，正相反。因此，记住以上这些建议吧，有则改之，无则加勉！
