I think you can just say it. If the girlfriend has a bad temper, it is normal for couples to quarrel. There is a good saying, make a fuss, make a fuss. Girls always like to be willful. They just want to attract the attention of the male ticket and let the boys coax her. What girls quarrel with boys is only the attitude of boys, not anything else. You can just say you don't like chicken soup. You're tired of it.
Psychologically, girls are born with hug hormones. They like being hugged very much Hugging will make them feel happy and safe. You can just say that you don't like chicken soup. If she is angry, give him a warm hug as soon as possible, apologize sincerely and let her die for your warmth.
You can buy a gift before you speak. Never talk about girls' material things. Buying a gift is not how much you spend for her, but to prove your attitude of seeking kindness. In the eyes of girls, when they are angry, boys buy gifts for themselves to prove that you care about them. And boys always think girls are very material. Actually, it's not like this. They don't ask you to buy more expensive gifts, but care more about your attention to this matter.
Another way is to hit yourself while talking. Girls are very kind. If there is an argument and the female ticket is unhappy, just pretend to hit yourself with great strength. Girls will feel distressed when they see it. Who asked you to be her male ticket? Girls are soft-hearted and easily moved. When they see their male ticket to wake up their mistakes and beat themselves hard, when they see a boy like this, their first consideration is no longer their unhappiness, but your health.
