Sometimes the simplest experiences make the best memories. And, when you break out of the ordinary, the experience may end up "an entry in the family scrapbook," says Frank Farley, a psychologist at Temple. It's the coming together to try something new and different that underlies the bonding phenomenon, he says. "If you are doing something humdrum that you've done over and over in the past, that won't work," Farley says. "You have to do something novel, something a little different; then it becomes an adventure."
