I have been around kids all my life, and one will get you ten dad was right. what if the oldest had been a boy? I feel sad for kids whose parents freight kids with a load of current political garbage, when they have enough to work out already. Dad should have phrased the question in a guilt-free way, but she needed to take responsibility for her actions. Bigger kids push smaller kids around, smaller kids bite them for it. "That ye sow..." Nothing makes the point like a nice, painful, bite. By the way, the term "political garbage", in no way minimizes Mother's righteous concerns; just her need to infect what is a perfectly normal sibling event. The proper response would have been to admonish both kids for their  actions, with love, patience, and no expectation of their compliance, and resolve, in future, to check your crusader's weaponry at the door, and stop stinking up the lives of little children with these things.
