The fortune teller said that our son's parents were gram-positive. Is there anything to prevent gram-positive?

That's bullshit！ The so-called "gram" is not the gram you understand. Children let their parents worry, also called "grams"; When the children are not satisfied with their study and work outside, parents at home are worried about their children's feelings, which is also called "gram", and so on. You can call "gram" to let nature take its course. Don't worry, believing what others say will affect the feelings of father, son and mother. Besides, the gentleman you mentioned is very accurate?
