The fact of the matter is without knowing the specifics of the situation that's being discussed one can not say if it was a bad judgement call on the part of the father or just a kid being a kid and doing what they wanted opposed to what they were told they were allowed to.
Oh stop.
The 3 year old was gone for 45 minutes and the Dad had no idea where he was. If I were his wife, I would slap the #### out of him, then take every single penny he had in the divorce settlement.
