Sister and mother are in conflict and caught in the middle.

1, coax your mother first, say something about you, or share your mother's thoughts and tell jokes with happy things at school or among friends. Anyway, just don't let mom keep angry with a straight face.

Trust your sister, don't bother her by phone all the time, and let her think quietly.

Find your sister's good friend, care about her, don't persuade her, just listen to her, which is equivalent to exploring what she thinks.

Talk to that man and see how he treats your sister, and ask him to persuade your sister to go home. I think if he didn't persuade your sister to go home, but incited rebellion with his parents, such a man would have dumped her long ago.

The average boyfriend will succeed if he is persuaded.

Everything has to wait for your sister to come home, so everyone can talk calmly. That man had better leave. I have a brother-in-law. At first, he didn't agree, so he went to my sister's house every day to beg. Don't be too happy now.

Being nice is the most important thing, not to mention your sister's own fancy. It is good for two people to be happy.

Above all, no matter how right you think your sister is, you must stand by your parents. There is not a mother who does not want her children to be happy. If your sister and that man both feel that they must be together and will stick to it, then you can secretly help them and make your mother change.

I also have a younger sister who has a similar situation, but the man gave up first, and my sister looked very hurt. You must improvise, but don't break your parents' hearts. The most important thing is to let the two sides communicate well, and parents must not make trouble without reason.
