Did you grow up with or — let’s be real — do you currently know a “one-upper?” You know the type: You ran a 5-mile race. They ran 10. You baked cookies for your kid’s bake sale. They whipped up cookies and brownies. The concept isn’t a new one. People’s natural competitiveness comes out to play in any situation involving a power dynamic. But since I became a mother, I feel as if the one-upping has taken a weird and dark turn.
