Older Sibling

She/He is somebody who ignores the rest of the family, gets the better grades, but hates the younger siblings. They always get annoyed by the rest of the family. The only good thing about them is they are ussually generous,

Person 1: " My older sister is the best. "
Person 2: " So she gives you stuff? "
Person 1: " Most of the time. But she does ignore me. "
Person 2: " She is FR older sibling. "
Person 1: " Fax. "
