Christmas day, in my family, consists of the three siblings (me and two of my brothers), a few family friends and our various partners and offspring. With our parents both deceased, we take turns hosting the big day and everyone contributes something to the meal.
Abusers don’t like boundaries. They hinder their progress in getting what they want. Consequently, they choose their targets very carefully. Children make excellent targets because they don’t have many options, they’re eager to please and require the love and attention of their caregivers. Children of abusers grow up not understanding their worth, or the concept of boundaries in relationships.
