Okay kiddo, you know how sometimes you scream really loudly when you're scared or upset? Well, imagine doing that, but not making any noise at all. That's called a silent scream.
Sometimes people can have really strong feelings or emotions, but they don't want other people to know how they're feeling. So instead of making a noise, like a regular scream, they keep their mouth closed and make the scream inside their head.
It might look like they're just sitting there quietly, but inside they're screaming and yelling as loud as they can. It can be a way for them to cope with their emotions without drawing attention to themselves.
It might not seem like a big deal, since you can't hear anything, but it can actually be really intense and overwhelming for the person silently screaming. They might feel like they're suffocating or like they can't breathe.
So if you ever see someone who looks upset or angry but isn't making any noise, they might be having a silent scream. It's important to be kind and understanding, even if you can't see or hear what they're feeling on the inside.
