Young children and some older children call their parents either mommy or daddy. But most of the time grown-ups usually call their parents mom, dad, ma, and pop.
Children during World War 1 did in fact call their parents Mummy and Daddy. There have been many variations of what children have called their parents including; Mom and Dad, Mommy and Daddy, Mother and Father.
It would be unusual for parents to call the cops on their child for doing nothing. However, if there are other underlying issues or concerns, they may involve law enforcement as a last resort to address the situation. It's always best to communicate and try to resolve any conflicts or misunderstandings peacefully.
I think they call them Amma and Appa but I'm not quite suree :/
