What made Mr. Bumble miserable in Oliver Twist?

What makes Mr. Bumble miserable is his marriage. This parochial beadle might like to lord it over the half-starved waifs in his "care" at the workhouse, but at home, it's his wife who's firmly in control. An aggressive, domineering woman, Mrs. Corney makes her husband's life a misery with her constant nagging and criticism. She's also not above a little physical violence.
In one particularly humiliating episode, Mrs. Corney throws a bowl of soap suds at Mr. Bumble's head, and right in front of the workhouse kids, too. Bumble slinks away like a wounded animal to the sound of ill-suppressed giggling from the raggedy orphans. No wonder he's miserable. Where once he was feared, now he's become nothing more than a gigantic laughing stock, a rare source of amusement for the workhouse children.
