amicable - friendly
The term ‘amicable’ is typically used in the contexts of relationships or agreements, describing something that is peaceable and good-natured despite the high possibility of disagreement or rancour due to the difficulty of the situation. In that regard, it can be seen as being a positive within an overall negative.
