One of my cousins threatened to kill his mother repeatedly.
Where I worked we had a man who constantly said he would like to kill the plant manager (The Plant Manager from HELL!).
He went into detail of what he would do and how he would dispose of the body.
Everyone laughed because he was a loudmouth.
But everyone was leery of a nice small quiet man who worked there. There was something not right about him even though he was a church going person.
He even had the toughest equipment operators shook.
