Straight up! Parents turned grandparents who in their early marriage was toxic, one was a Nagger (wife) and the other was extremely cool and secretive.

Her domineering nature was something you'll find in another planet, but her free giving nature is a complement.

Both seldom have quarrel such that the children (Adults) are mediators in their feud. Many a times they are the judge ( incorruptible). The married ones especially female still marvel on their matter

The question!

Is it cool for parents, especially grandparents to expose their quarrels to the face of children, grandchildren, in-law, n family members?
