4. Don’t let them clean up after you
This point is for both males and females, not just ladies alone. You’ve finished eating and you expect your soon-to-be in-laws to clean up after you? That’s a recipe for disaster. They will definitely not like you. Instead, ask for the kitchen and insist on washing your bowl/plates and theirs as well. When they insist that it’s alright, help send the items to the kitchen and stay there. Even if they won’t let you wash them, you might be allowed to rinse them.
