In front of the people we love, sometimes we feel childish because we want to show our truest and most vulnerable side in front of each other, hoping to get the other party's attention and love. Maybe it's because we feel nervous and uneasy inside, so we want to relieve our emotions by showing childish behavior. This kind of behavior may also indicate that we have deep feelings for each other and want to express our dependence and needs for each other through our actions. We may act childish because we want to build a closer relationship with each other. This is a way to express our feelings. No matter what the reason was, this kind of performance was out of concern and love for himself and the other party, hoping to gain the other party's recognition and acceptance.
