White lie
The word “skunk” refers to a type of animal which has an uncomfortable smell. If one skins a skunk, his or her action obviously brings discomfort to him or herself. However, regardless of how challenging the work can be, that individual is still supposed to complete it on his or her own without receiving help from anybody.
