I find something wrong with this saying. If I don't mind people calling me bitch, does that mean I can call others bitch? I don't mind friends take my things without asking as long as they return it in good condition. Does that mean I can take their things without asking? I don't mind friends not returning me money owed to me, does that mean I don't have return money owed to them? IF I don't mind people sleep with my wife, does it mean I can sleep with others' wife?
But he can do the same to me, I won't mind
I have heard this many a time. I used to think it's a reasonable excuse. Now I am not so sure. Especially that when the person heard this excuse, it's too late, the damage is done.
There's also a twisted version of this saying. "Do unto others what they do unto you." Revenge. He's always slow in replying my sms, I shall also delay in replying his sms. He always say mean things about me, so I don't want to see him ever again. He spread rumours about me, I also spread rumours of him. He steal my girlfriend last time, so I fool around with his this time. There's no hope for the human race.
