My wife asked me to pay something for her, and her attitude made me very unhappy. How can I get back to a better state?

Girls only have this attitude towards their closest family members, which is a "willful time" in front of you.

I suggest that this cosmetic is not expensive either, so I'd better buy it for him.

After paying for him, she must be happy to go home. You are taking the opportunity to raise the question of his attitude, so that your daughter-in-law will be happy to accept your suggestion and will pay attention to her attitude next time, which will be more effective.
