APAD: Get a taste of your own medicine

The idiom "get a taste of your own medicine" means to experience the same unpleasant treatment that someone has given to others.

Example in a sentence: "I don't feel at all sorry that people are calling you names. You're getting a taste of your own medicine".

The idiom comes from an Aesop's fable about a swindler who sells fake medicine. When the swindler gets sick, people give him his own medicine, which he knows won't work.

I think the idiom corresponds somehow and someway to Chinese saying: 己所不欲勿施于人，若施于人苦果自得。

Looking at a different angle, if one can consistently do good things and help others in need, he or she will get the same kind treatment from others, right? 
So "every coin has tow sides", and a dice has 6 (or more )

Happy another Thursday my friends.
