As a child, Lin Wan asked her mother with wet eyes: Mom, why does my sister pinch me? It hurts! Little Lin Wan rolled up the sleeves of her clothes. There were red pinch marks on her thin arms under the sleeves, which looked shocking.
Mom gently put down her sleeves to cover the marks. While busy with the things at hand, she lowered her eyes and said: Be good, sister, she just likes you so much.
Does it turn out that if you like someone, you have to pinch them? Little Lin Wan thought so in her heart.
When Lin Wan grew up, when she met someone she liked, she expressed her love clumsily as in her memory, but why, mother, was it different from what you said.
