A good general rule of thumb for life is ‘thou shalt not mess with a man’s daughters, especially if you are within proxy of the man’s fist/sword/wrath/musket.’
Those of us who watched Mel Gibson’s ‘The Patriot’ saw a movie based on that theme. An entire regiment of British troops met their maker because one British colonel decided to mess with some colonist’s kids.
This drunken guy is receiving a good ol’ fashioned continental beat down from an angry Dad. He should have known better than showing up drunk to a beach and messing with a man’s daughters. Done.
