Make her the perfect cup of coffee! Coffee releases happy hormones and makes u more active. It's perfect :)
Ask her ,her fav dishes. Make it. & tasty too. Only that way ,u can impress her. It s not necessary ,what u make is her fav dish.whether it s for breakfast,lunch or dinner. Not only her taste,but other enjoyments,that too helps,while dealing with mother in laws. If she wants to go out or watch good movies on tv,things like that.
