Clark, the ultimate “work-hard, play-harder” type, booked our holiday flights—first class for himself and his mom, economy for me and our two kids under five. At the airport, he shrugged off my shock, leaving me juggling toddlers while they enjoyed champagne in luxury.

But I had a plan: I “misplaced” his wallet. Mid-flight, as my kids finally slept, I watched Clark panic when faced with a $1500 first-class tab. Groveling for his mom’s credit card, he shuffled back, defeated.

Upon landing, I slipped his wallet back, satisfied. Parenting isn’t a solo act; no amount of legroom can replace teamwork. Lesson learned: next time, he’ll think twice before indulging at my expense.
