Brother-in-law's costume fortune telling _ Brother-in-law's costume fortune telling is not allowed.

Brother-in-law disguised himself as a fortune teller

Even if what is said is true, since it has been decided that your sister will get engaged tomorrow, how can you say that you will not get married at this time? Men and women are not necessarily oppressive, but may be some kind of personality, some kind of behavior and so on. Don't care too much about this. Maybe your sister and your brother-in-law are happy after they get married.
