Every family has its heirlooms, whether they're stories, quilts, recipes, photo albums or just family resemblances.
According to Beau Weston, head of Centre College's sociology department, family reunions have been going on since nearly the beginning of time.
"Reunions have been happening since young people began moving away," said Weston. "The kids come back. It's a return to the original space after they've become sufficiently distant."
Weston said families are the foundation for people to interact and to provide support.
"You build up ties to the family during the 'green wood,' as the Bible says, by getting to know people," said Weston. "The obvious payoff is in the 'dry wood,' during a crisis when the family is there to help."
