Fussy sense is rather elusive. It refers to someone who is vitally particular and fault-finding. A persnickety individual often pay strict attention to detail and has high standards when it comes to quality and perfection. Their attention to detail can be viewed as laudable, but it can also magnify unwarranted censure and unjustified dissatisfaction. Being persnickety is frequently related to precise focus on specifics but can also be seen as a type of pedantry.
