Underhyped: The poor, unloved sibling who's always getting the short end of the stick. Nobody remembers to invite them to the party, and even if they do, it's just for pity's sake.
Overlooked: The sibling who's just too darn nice to rock the boat. Always trying to make everyone happy, even when nobody's happy about them.
Overrated: The sibling who's just too full of themselves. Always trying to one-up everyone else, even when nobody cares.
But, hey, being part of the unloved trio has its perks! We have a great system of support... for each other!
