[BradfordGirl]

I do not think they are nuances or good reasons for violence between adults in a family. It is always wrong.

I've never hit anyone but if I were going to hit someone, it would be my sister. I love her very much but no one presses my buttons like she does.

and @BradfordGirl refers to her “arsehole” of a brother

one wonders the poisonous verbal exchanges these siblings have exchanged
