What does it mean that parents are like stepbrothers?

Hello, this sentence literally means that parents are like passers-by to themselves, but they have a thin relationship with their brothers. This sentence is often used for divination. Most of them are not very good descriptions. In this case, I suggest you get along well with your family as much as possible. It's no big deal. However, fortune telling is also easy to be blindly believed. Everyone's life is mainly about themselves. Don't be superstitious, believe in yourself. I hope my answer can help you.

Wish you all the best.
