Your wife decides to go out with her friends drinking and dancing….You’re okay with it, because you get to watch sports and play on the Internet all night…
You hear her stumble into bed around 4 and laugh knowing she’s going to have a monster hangover….
You wake up next morning and go outside to the family Volvo, which she used last night….
You sigh in relief because it’s all in one piece….
You circle the car looking for dents and find none….
But …. Wait a minute….

[obviously a role reversal here would be more credible!]
