For Marco and Mia, Sasha and Theo, Richie and Adam, the one constant in life after college together has been change. New jobs. New cities. New spouses. New children. Through it all, one thing they thought would always stay the same is their friendship. But time has a way of breaking even the strongest bonds, and testing what we thought we knew. From East Village apartment parties and disastrous destination weddings, to 40th birthdays and suburban backyard barbecues, SO OLD, SO YOUNG is a story about the growing pains of the Millennial generation, and a celebration of how love can shift, stumble and grow into something bigger than we ever could have imagined.
