The fortune teller said that my brother's first child was a girl, and my partner and I were also girls, right?

Fortune telling and horoscope are Barnum effects, which means telling you some common characteristics of everyone, and then you will feel very accurate. For example, I am a fortune teller. I said that you don't like being arranged and guided by others and have your own ideas. This sentence is valid for at least 98% people, and you will think that he is very accurate. Further, you will believe other things he said, such as giving birth to boys and girls. You must be a liar.
