Demanding definition is somewhat tricky to comprehend. It refers to someone who is immensely selective and judgmental. A persnickety individual tends to pay strict attention to detail and has high standards when it comes to standards and flawlessness. Their fastidious nature can be seen as admirable, but it can also intensify excessive disapproval and superfluous dissatisfaction. Being persnickety is frequently connected with thorough attention to detail but can also be seen as a manifestation of obsessiveness.
