Children, like adults, can sometimes say or do things that may come across as rude, but it's essential to remember that children are still developing their social skills and understanding of appropriate behavior. They might not always have the same filters or awareness that adults do. Instances of "rudeness" from children can vary widely and may range from unintentional bluntness to acting out due to various reasons like stress, fatigue, or unfamiliarity with guests.
It's essential to approach children's behavior with understanding and patience, gently guiding them toward appropriate behavior and communication while considering their developmental stage and perspective.
