Vicky: Did I imagine it or did you just give Gavin the cold shoulder?

Give some one cold shoulder=故意冷落某人

Gerard: You didn’t imagine it. I’m not too happy with him. Vicky: Why? What did he do?

Gerard: He’s two-faced, that’s why. Last week, he told me he was going to put in a good word for me with the manager for a promotion.
因為他是個兩面派。上星期，他說他會為我升職的問題在經理面前說好話的/勸經理升我的職的

。
1.Tow-faced: 兩面三刀的，兩面派，居心不良的，明一套暗一套，當面一套背后一套，別理解成墻頭草了。
2.to put in a good word:說好話、美言

Vicky: So that sounds like a nice thing to do. Gerard: I thought so, too. But as it turns out, I heard from Elanda that he was bad-mouthing me behind my back.
我也這么覺得，可結果呢？我聽Elanda說他在背后說我壞話呢
