While reading a novel I've found this expression:
bolt from the fold
Does anyone know what it means?
Here is the whole sentence to provide some context:
It is possible that Godfrey found the lifestyle more than a little alienating, for, sometime during the course of his studies at Fargo Congregational College, he bolted from the fold and, to the enduring agony of his parents, fell into worldy pursuits, and ended up, somehow, getting a Ph.D. in Classics from a small private university in Ohio.
