你说的所谓谦让的办法, “你看，本来应该。。。。，但我。。。）”，美国有个成语，叫做：
Don’t negotiate with yourself. "One of the things they did teach us at law school about negotiating is, don't bargain against yourself," she said. "If you say you want $190,000 and the other person says that's well beyond the range, don't come back and say, ‘ How about $150,000?’ Wait for their response; don't bargain yourself down."

You know, when you offer a price in either a purchase or a sale, and in the process the other party reacts, but remains silent. What is your normal inclination? To break the silence . . . and often times the first thing you will say is, “well, I could accept a lower price or make a higher offer.” I am sure every one of us has been caught up in this scenario. In fact if you have every been asked to offer your “highest and best” offer, you have more then likely been caught up this obvious trap. https://www.biggerpockets.com/renewsblog/2012/03/02/negotiating-101-bid-against-yourself/
谈判的目的不是吵架，而是解决问题。你直通通地说，你给我二千，少一分钱我就去告，对方只好说，那你去告好了。
解决问题的方法，是给对方充分的选择，把多个对立选择都提出来，给对方足够的选择让对方组合一个解决办法。这不是攻击性，这是谈判的步骤。
