I know mostly of us were familiar with this words "blacksheep of the family". But sometimes they are the most needed some attention. They're having trouble in some ways. But we should check our own sister/brother if they are ok. So they wont get wrong or be in trouble. What matter is the affection and care with each other.
Example
Definition: The oddball member of the family who does not fall in line with the others; the worst member of the family.
Also used as the shortened phrase black sheep, the black sheep of the family is someone who makes bad decisions or has a bad reputation within a family unit. While the rest of a family may follow laws, the person who is the black sheep of that family may have been to jail or is simply the “odd man out” when it comes to family relations.
While often used to describe a person with drastically bad behavior, the phrase can also be used to describe somebody who does not fit in with his or her family.
For example, a girl who wants to join the cheerleading squad while the rest of her sisters and mother are all competitive swimmers may feel like she is the black sheep of the family because she does not fit in with them.
Origin of Black Sheep of the Family
define black sheep
This phrase may have originated from the fact that black sheep were less valuable than white sheep because their wool was more difficult to dye various colors.
This phrase can also be traced to the Bible. A 1535 translation of the Bible includes the phrase “all blacke shepe amonge the lambes” [all black sheep among the lambs] in Genesis 30:32.
In this biblical sense, Jacob is negotiating a wage from Laban. Sensing Laban’s extreme selfishness, Jacob proposes that he be paid with animals, not with money, and that he will accept only the black or speckled sheep. Of course, that vast majority of sheep are white, so his pay would be very little.
Additionally, in the 1600s, Religious Puritans who immigrated to the Americas began using this phrase to describe people with unwanted behaviors.
