If you go to somebody's house for a barbecue, it is only a matter of time before a guest has six beers and begins to inveigh loudly about how the institution of marriage is a sham, how it's a violation of nature's will, how monogamy is an outmoded expectation that might have made sense for power-consolidating families in AD 600 but makes little sense now, when there's you know, high school flames you can look up on Facebook. This well-versed marriage critic will then burp loudly and fall asleep in a lawn chair for the rest of the night, which says all you need to know about his marriage.
