Reporting something wrong feels like snitching until you realize silence was also picking a side.

Telling someone feels like breaking a rule, because groups tend to carry an unspoken one about not telling. What that rule actually protects is whoever is doing the harm, and staying quiet is not neutral even though it feels like the neutral option. Silence leaves the situation exactly where it is.

If someone is being hurt, go to an adult you actually trust rather than the nearest one. You can ask for it to be handled without your name where that is possible. If the first person does nothing, try a second, and none of what happens is your fault.
