Adulting is hard. You have to deal with paying all of your bills on time, making sure children or pets are fed and watered, keep your house clean, remember people’s birthdays, and deal with car maintenance. It’s enough to make you want to go to bed in your pajamas in the middle of the day.
So this guy should maybe have expected the response from his wife in this conversation. I’m sure more information was forthcoming, like whether she was at the garage because she’d had a crash, or because the car had made a funny noise. Either way, it means more money, and more adulting.
