There's nothing like a trip to the supermarket to remind a person that being single isn't so bad. I was at the self-checkout and had a front row seat to a couple in their forties arguing over their inability to operate the scanner. More to the point, it was her loudly berating him for any attempt he made to help. The most amusing aspect of the whole thing was the clerk standing directly behind them, chuckling, rather than offering any assistance.
Is it really a requirement for married couples to spend every waking moment together, even when undertaking the most menial of tasks, such as grocery shopping, and even when they are so obviously incompatible in a public setting?
