When I go to my girlfriend's house for the first time, my prospective mother-in-law will always look at you to see if this boy is suitable for her daughter. If your prospective mother-in-law doesn't cook well, you can say it to her face or stop eating after a few bites, which will definitely make her uncomfortable. If your mother-in-law is uncomfortable, her impression of you will get worse. Your girlfriend won't put in a good word for you in front of her.
If it's not your first visit to a friend's house, you already know that the mother-in-law-to-be cooks badly, so why don't you cook by yourself? If you can cook, go to your girlfriend's house and tell your prospective mother-in-law that you are coming to cook. Even if your future mother-in-law won't let you do it, you must find an opportunity to do it this time. Because you won the opportunity to cook, you can not only eat delicious food, but also leave a very good impression on your mother-in-law and father-in-law.
If you can't cook, you can teach yourself several dishes at home. Only when you learn how to cook these dishes will they taste good. Next time I go to my girlfriend's house, let my mother-in-law rest and cook some dishes in the kitchen. In this way, you don't have to eat the terrible food cooked by your mother-in-law, and you will be praised by your mother-in-law for cooking delicious.
