Today you watched your mother in law hit your little girl in the face for making a long, loud, irritating noise at dinner. Stunned, you said nothing. Instead, you removed your child from the situation and offered a distraction to all parties. This was perhaps not the most prudent course of action.
Tomorrow, you will do better. You will not allow this to happen again. Your daughter was not hurt physically in the slightest– it was a light slap– but she was definitely hurt emotionally. You will do a better job of protecting her spirit, and somehow manage not to make an elderly woman feel badly in the process.
In the future, when you are elderly, you will remember to patient and tolerant of children. You will never strike someone else’s child in anger. You will remember this incident in which you failed your child and will not put another mother in a similar situation.
