Yeesh!
Talk about having just been run over by the crazy-train.
Has the woman never seen a family tree? Does she not realize how EXPONENTIALLY BIG they get when all of a sudden one includes "everyone" I'm related to???
You and your husband come from 2 different families.
Just because your side of the family commissions a family portrait doesn't mean that ALL the inlaws, and then all their inlaws, and then all their in laws, and all their inlaws (ad naseam) ALSO have to be in the family portrait. If your family is anything like most people's families... that's 200 people. If you're from a family like mine, that's 500 people.
Your Sibs + Their Spouses + Each and every single one of their families + all of their spouses + their families = apx 100-500 people.
Then add
You + Your Spouse + His family + Their Spouses + Their families = apx 100-500 people.

Her BROTHER'S INLAWS were having a family portrait done. I have 2 married brothers. I looooooooove both their wives, and the family of one of my SILs. I'm 2 steps removed from their family, though!!! To throw a "you don't love me" fit over her brother's inlaws not including her and her family? I really, really, really hope she's pregnant.
