There's always one couple who almost break up every time that they're out. She looked at another guy for longer than she should have and her boyfriends isn't paying her enough attention; basically, their fights are fit for a slot on the Jeremy Kyle show, with lie detector tests and results. Now whilst it's only polite to give couples their space when they're going through a tough time, they're arguing (loudly) in front of everyone, so it would be rude to not pick a side and support them. Now whilst the original argument has stemmed from some jealously by one party, you can guarantee that it will turn into a fight involving every mistake that they've ever made being thrown in their faces.
