idiom of the week

If there's one phrase to learn tis week, it would be this.

对牛弹琴 duì ​niú​ tán ​qín​
· to play the lute to a cow (idiom); fig. offering a treat to a unappreciative audience
· to cast pearls before swine
· to preach to deaf ears

well, i guess i've been getting a lot of this lately. enough is enough.

lesson learnt: if you want to behave like a cow, i wont bother to treat u humanely.
