Task: are negotiations for weak people?
In certain way negotiations are meant to be a remedy for people, to help them meet each other needs throughout reciprocation or logrolling, finding common ground in the known to be deserted areas of business or relationship. But your attitude towards this method of solving the upcoming issues is irrelevant unless you've been practising it for years.
A s for the weak people, they are considered to be vacillating in commitments and always try to amend the things that have been done ages ago. They are reluctant to make first step, and it seems so that no one, who's not strong enough, doesn't seem to be capable of making any use of negotiations.
Should it be win-win arrangement in your mind, it's always win-lose in the tough reality.
