Despite being the younger sibling in the family, this 25-year-old was often considered the most responsible person in their immediate circle (that includes her parentS). Her older sister, who clearly does this out of some sort of a defense mechanism, frequently refers to her younger sibling as “Mom Junior” and even more recently as the family “buzzkill.” The younger sister usually brushed off these “jokes,” but after a while, their mean-spirited nature started to eclipse any genuine attempt at being funny. By the time the older sister made a similar joke about the 25-year-old during her wedding speech, it was inevitable that things were going to hit the fan.
