etiquette doesn't just mean rsvps and dinner party manners, it's a reflection of your entire outlook on social interaction and public life. not holding the door open for a little old lady says something about you to everyone who sees it -- namely, that you can't spare five seconds to be a half-decent guy。

　　所谓礼仪，指的不仅仅是答复邀请、或参加晚宴时的优雅举止，它能反映出你在社交场所及公众生活中的模样。举个例：一位上了年纪的老太在你身后进门，你却忘记帮她扶着门……那么，任何目睹了这一幕的旁观者会立马对你的印象大打折扣。

　　in most situations, your image and appearance isn't just part of what defines you; it's the only thing that defines you. people who don't know anything about you are going to fill in the blanks with the only information they have, which is how they see you behave. regardless of how you think of yourself, one awful social habit can easily become the thing that comes to identify you: anyone who sees you chewing your food like a cow and acting belligerent toward your waitress is going to remember that stuff far before your job title or sophisticated wit。
