This thing itself is that the girl's grandmother did something wrong. If children really want to play on swings, they can choose to discuss with boys. And this is in the park, everyone is qualified to play with this thing, so when others grab it, we can also choose to communicate with them. At that time, the girl's grandmother went to violently shake the number. If the boy falls, then the girl's grandmother should also bear the corresponding legal responsibility.
Fighting in front of children will also help children learn this way of dealing with things. It may be considered very correct in children's minds, so children may choose to do this when they want something in the future. As parents, we should use the right method to solve this problem in our children. Parents can let their children learn to communicate, instead of just using violence to solve problems after this happens.
The practices of these two parents are all wrong, and the behavior of both parents has also brought bad influence to the children, which will also lead to the children being influenced by their parents to solve problems in the wrong way, and will definitely suffer big losses in the future. If parents really think about their children, they should refuse such things.
