This is a refreshing perspective.
A fellow we know was complaining about having a hard time with the subway in Boston. I don't know, I guess he got turned around switching trains or something. "Ugh. It was the worst day of my life," he said.
"That's wonderful," my wife said. "You must have an amazingly easy life!"
Your wife sounds like a cool lady.
I've worked hard to try to just roll with the punches and take a deep breath when shit happens. People think complaining is a stress-reliever. It isn't. It just refocuses your attention back on what you're complaining about.
