In natural presence an actor sets a task to be accomplished. Often one has a clear image of what the conditions for fulfilment will be, and what the trajectory one has to follow will entail. Also, there is the mental and public image of what the success of an action will be like. To perform certain tasks well may seem simple, but even doing the dishes causes arguments in many households. The quality of work is always under debate. Arguments arise from issues like: good functioning, transparency of work, efficiency, beauty, cleanliness, effectiveness, complexity, simplicity, transportability, time spent, money spent, solidity, and others. Such arguments include differences of opinion and also differences of interest and experience.
