Respectfully, LinusK, I am one of the "There but for the Grace of God go I" posters you refer to. I am not a perfect parent. At all. I am hyper vigilant, uber controlling (according to my kids), well educated and fairly intelligent? yet I have managed to make mistakes that could have had dire consequences. Fortunately, my children did not go into a gorilla exhibit in a zoo resulting in the death of a primate.
I can't equate Ross Harris's actions with this situation at all. It comes down to intent IMO. I don't believe for one second this mother intended for her son to go into the gorilla enclosure, nor did she intentionally ignore him.
Truthfully, if I were to reveal all the mistakes I have made as a parent over 28 years, I am afraid of the bashing I would receive and that would be devastating for me. I have already beat myself up enough. Whether this mother has self awareness or not, I can't begin to bash her or judge her harshly. I don't know of one single perfect parent, however I have tried to learn from experience what I should or shouldn't do so I don't repeat my mistakes.
Initially, I said "WhereTH was the mother?" when first reading of this incident. With more witness accounts and reporting, I realized that this could happen to anyone (hopefully not). I respect you and your position and I hope I you can respect mine. Xo
