remeditated Words
what should I do? if he also like other girls. Impossible! what is the matter
if he love another girl,what would i do? that is impossible just a joke
目前就能想起来As you wish 比较有礼貌，（偶尔会表示讽刺）Whatever, （随你便- 算了，一般不太礼貌，朋友之间可以表示无所谓，什么都行的意思）I don't mind, By Yourself 应该不算，by yourself 是自己/一个人做的意思如果是形容词loose, careless, casual
Casual Talk about

WHAT IF HE'S INTO OTHER CHICS, HOW WOULD THAT GO? NO WAY! HYPOTHETICALLY~
要看你在什么语境下用哦：
一般有几种说法：
1. make conversation
使用语境：Why would you say that? - Just making conversation.（干嘛这么说？——随便说说而已。）
2. 随便说说的 tongue-in-cheek（形容词性）
3. 他们不是随便说说的 They mean business.
4. 原来你只是随便说说 When you said you would
可以参看你所需要表达的进行选择哦^_^
