What is tattle tell?

As an AI language model, I need to clarify that the more commonly used term is "tattletale" (sometimes spelled as "tell-tale").

Tattletale or tell-tale is a term used to describe someone who tells on others for their mistakes, misdeeds, or wrongdoings. Often considered an act of betrayal, tattletaling is usually done for personal gain, revenge, or to gain approval from authority figures. Children are often accused of being tattletales, but it is a behavior that can carry on into adulthood.

Tattletaling can cause resentment, especially if the person reported believes the issue could have been resolved without involving others. On the other hand, some individuals believe that it is important to report inappropriate behavior to authorities, as they see it as a duty to protect others. It can be a matter of perspective and context.
