All of you would be wedding guests know that attending a wedding can be stressful. Wedding etiquette demands that your attention remain focused on the bride, but what about the pressure it puts on you and your budding relationship? Tango investigates. "Any bride will tell you—at great length—how stressful it is to plan a wedding. But what about the guests? Rarely does anyone acknowledge their pain. Every year there are around 2.2 million weddings in the United States, and roughly 300,000 weddings here in the U.K. Multiply that by the length of the average guest list—about 200, in both countries—to get a sense of just how many of us go through the familiar routine: pick main course, pick present, pick outfit, pick date. If you’re in a serious relationship, the last choice is already made for you, but you can still find yourself picking—at each other. The truth is that these lovely, sacred events—opportunities for voyeuristic romance and, hopefully, some amour of your own—often wreak havoc on relationships that are, shall we say, at the tipping point."
