Brother and sister are both adults. Is it appropriate for a brother to hug a sister and a princess?

The answer to this question will be different due to factors such as culture, family and social environment. In some cultural and social environments, the relationship between brother and sister may be closer, while in other environments it may not be appropriate.

From the perspective of general social norms and etiquette, physical contact between adult brothers and sisters, such as princess hugs, may be considered inappropriate or inappropriate. This is because, after adulthood, the relationship between family members also needs to maintain a proper distance and respect to avoid unnecessary misunderstanding or offense.

But the specific situation also needs to consider the feelings and relationships between brothers and sisters. If brother and sister have always maintained a close relationship, and this behavior will not cause any trouble or discomfort to anyone, then this behavior may be acceptable.

In short, whether it is appropriate or not needs to be judged according to the specific situation, and many factors such as culture, family and social environment need to be considered.
