What if on Christmas next year I make a social blunder and my aunt goes ballistic on me?

She is nice lately because menopause is past but she used to be extremely abusive when in menopause. She does have a life history of making blunt comments about others that can be insulting and hurtful even pre-menopause. She hates my Mom, her sister. 

?: Only if they involve Christmas. I have Obsessive-Christmas Disorder. It is very difficult to live with.
