First, eye cues and action cues Parents can use eye cues or some subtle action cues when educating their children. Because when children do something wrong, or parents want their children to do something, sometimes they just need a look to give it to their children, and children can clearly know their parents' thoughts. For example, if the child doesn't go to bed at 9 pm, parents only need to look at the clock and the child will know it's time to go to bed. Parents can also hint their children through actions, use some body language, express their thoughts, and then educate their children. For example, if a child doesn't go to bed at 9: 00 p.m., parents can help the child make a quilt, and the child will know it's time to go to bed when he sees the parents' actions.
Second, the expression implies that sometimes parents' expressions can make children understand their parents' feelings better than their eyes, because people's expressions can convey a lot of information, and many psychologists will understand people's psychology by analyzing people's micro-expressions. Parents can also use expressions to hint at their children when educating them. For example, if a child does something right, parents can give the child a smile or a nod, and the child will know that he has received it, which is definitely a great encouragement to the child.
Third, the words imply that many people are puzzled. Isn't verbal suggestion explicit? Actually, it is not. Oral suggestion means that you can't say what you mean directly, but express it in a euphemism. For example, when children do something wrong, parents can talk to their children about other children and emphasize how other children are doing in this respect. After receiving verbal hints from parents, children will know what they should do.
