fool around (with somebody)

　　To have a sexual relationship with another person’s partner; to have a sexual relationship with somebody who is not your partner. 这里翻译成鬼混也OK，毕竟人家两个人都是单身嘛!它的同意表达是mess around，例如：

　　She’s been fooling / messing around with a married man.

　　put something aside

　　这个短语有常见的两种意思，第一种就是剧中的用法，表示to ignore or forget something, usually a feeling or difference of opinion，例如：

　　They decided to put aside their differences.

　　第二个意思呢，就是to save something or keep it available to use，经常跟“金钱”或者“时间”连用，例如：

　　We put some money aside every month for our retirement.

　　I put aside half an hour every day to write my diary.

　　这两种意思都可以用set something aside来替换，例如：

　　She tries to set aside some money every month.

　　Let’s set aside my personal feelings for now.
