Learn to speak with reservation 说话要留有余地，因为话说绝了就没有退路了

Learn to speak with reservation. Otherwise,

there will be no way back.
Xian'er says so: Seeing through without telling.
Xian’er said to himself:

I made such delicious ice-cream but no one even noticed.

I won’t make ice cream anymore.

Wang Xiaowu always messes with me,

and I’ll never talk to him anymore.

Never! Shifu does not take me with him aboard,

and I will never sign up for overseas trips. Never…
Xianyi said: Hey, Xian’er, this is what you say every year.

But you never stop making ice cream.

Whenever Wang Xiaowu is here, you hang out with him.

And you ask about overseas trips every year.

It does not seem that you are not interested in going abroad……
Xian’er said: Xianyi, come on!

Even if you know it, why do you have to tell it like it is without saving me any face?

Remember what Shifu taught us?
Xianyi said: What happened?

How is the story making a turn?

Below are quoted from my Shifu’s new book, Say Good Things—Master Xuecheng’s insight on the path to speaking like a Buddha. 
What Buddhism teaches regarding not speaking much is based upon
how to benefit others, not the self.

A Bodhisattva takes the other person’s position,

not his own, when considering something.

As conditions are forever changing, speaking without reservation may hurt others when conditions change in the future. 

说话要留有余地，因为话说绝了就没有退路了
贤二如是说：看破不说破
贤二说，我做的这么好吃的冰激凌，竟然没有人捧场，我以后再也不做冰激凌了。王小五整天跟我找茬，我以后再也不理王小五了，永远。师父不带我出国，以后再有出国的事情，我坚决不报名，永远……
贤一说，喂，贤二，这话你年年都说。但是你年年也没有耽误做冰激凌啊；每次王小五来，你都跟他打的火热啊；而且年年你都打听国外的事情，好像不是真的不想出国吧……
贤二说，贤一，拜托你看破不要说破好不好，给人家留一点面子，
师父平时是怎么教我们的。贤一说，怎么搞的，这个故事怎么转成这个样子了。
以下来自我师父的《好好说话》
佛教讲的惜言，是建立在利他基础上的，不是利己。对菩萨道来说，
他在考量一件事情的时候，是把自己的利益抛开的，首先是站在对方的立场上考虑问题的。
因为因缘在不停地变化，如果今天把话说尽了，若以后产生变化，就会伤害到别人了。
