difference

　　这个词在这个语境下的意思跟我们最早接触的“不同”不一样哦。这里，它是a disagreement between people。比如：

　　We have our differences, but she’s still my sister.

　　Why don’t you settle your differences and be friends again?

　　There was a difference of opinion over who had won.

　　piss somebody off

　　下次想说“你真是气死我了”，就不要用angry之类的，改成You really pissed me off. 或者像上面说的：I’m so pissed off at you!

　　get something off your chest

　　就是“把憋在心里的话讲出来，一吐为快”(to talk about something that has been worrying you for a long time so that you feel less anxious)。

　　Why not tell her how you feel? It might do you good to get it off your chest.
