She will challenge your perspectives, especially when they don’t align with hers. She will argue with you, and make you see things in different ways. She will teach you the power of balancing two personalities to make a relationship work. And she will let you know when you’re not treating her right, not taking things seriously, or not putting forth your best effort. She’ll make you a better man just by her sass and letting you know how things really are, rather than skirting around the truth.
