"there must be a sense of proportion and moderation." I heard this expression from a Tv show called, Mentalist. "but there must be a sense of proportion and moderation." In Korean, there's an expression that is so common, so probably 9 out of 10 people might say the same one: "~정도가 있지." (I used it in an informal form) i.e.) 힘들다고 해도 정도가 있지 "I understand it's hard. but there must be sense of moderation." do you have one like this in English ? if not, please try to rephrase it. the better natural one to say , the better p.s : plus, if you could correct my grammatical error or just using wrong expression, that'll be appreciated!
