总之,大道至简。不能按简单的道理做,只好按不太简单的方法,以此类推。Be nice to your loved ones, be nice to your friends or even people you don't know. Then, people will be nice to you respectively.
其实,一个英文段子就够了:
"A husband is supposed to make his wife's panties wet,not her eyes. A wife is supposed to make her husband's dick hard, not his life.."
